The next four months are set to be busy for Apple, with iPhone 6, iPhone Air, iPad 6, iPad mini 3, new Apple TV, iWatch, new Macs and more expected to launch soon. Apple executives have been hinting at new product categories for more than a year now, and we can't wait to find out what they are. Plus, Apple has confirmed a 9 September special event so we know there's not long before we get our first look at whar Apple's been working on. Here, we explore all of the Apple launch rumours for the rest of the year and beyond, so you'll know what to expect from Apple.

2014 Apple launches: The story so far

So far in 2014, Apple has unveiled iOS 8 and OS X Yosemite, in addition to small updates to its iMac, MacBook Pro and MacBook Air line-ups. It used WWDC 2014 to focus on its software, which is undergoing some huge changes this year by becoming more open than ever before.

The small Mac updates are likely a result of the delay of Intel's next generation Broadwell chips, which we expect will now be introduced to Macs next year.

On 28 August, Apple sent out invites to a 9 September event, which we expect will play host to the iPhone 6, iPhone Air and maybe even iWatch unveiling. Read on to find out more.

iPhone 6 event invite

Apple rumours 2014: iPhone 6

We're completely certain that a new iPhone is coming this year, most likely at Apple's 9 September event. We're expecting to be able to buy the iPhone 6 from 19 September, 10 days after its unveiling.

Reports suggest that the iPhone 6 could have a display that measures 4.7in diagonally rather than the 4in boasted by the iPhone 5s. It's expected to have little or no bezels surrounding the screen, as well as camera and processor boosts.

We have a whole host of iPhone 6 rumours over in our iPhone 6 rumour round-up. Plus: Here are the craziest iPhone 6 rumours we don't think we will be seeing this September.

Apple rumours 2014: iPhone Air

Further still, speculation points to two new iPhone launches this year, the second being an even bigger iPhone measuring 5.5in diagonally. Many reports say that the iPhone 6 (as described above) and this bigger iPhone, dubbed iPhone Air or iPhablet, will arrive separately.

There are also lots of bigger iPhone rumours in our iPhablet rumour round-up.

Apple rumours 2014: iPad Air 2/ iPad 6

Another device we're pretty certain will arrive this year is a new iPad Air. We're expecting the next iPad to arrive in October, based on Apple's product launch history.  Find out more in our iPad Air 2 rumour round-up.

Apple rumours 2014: iPad mini 3

Can you believe we're talking about the third generation iPad mini already? Like the iPad Air, the Retina iPad mini (iPad mini 2) was launched in October so we're expecting a new iPad mini in October 2014.

Here's our iPad mini 3 rumour round-up.

Apple rumours 2014: OS X 10.10

Apple unveiled Mac OS X 10.10 at WWDC 2014, which it called 'Yosemite'. As expected, Apple took some design inspiration from the iOS 7 redesign for Yosemite, and we think it looks great.

You can expect to get OS X Yosemite on your Mac this autumn, possibly in October. Find out more in our OS X Yosemite release date article.

Apple rumours 2014: iOS 8

Apple has confirmed that we'll get iOS 8 on our iPad, iPhone and iPod touch devices in the autumn of this year. New features include HealthKit (iWatch hint?), as well as lots of improvements to the Notifications Centre, Safari, Messages and more.

Apple rumours 2014: Retina MacBook Air

It's been rumoured for a while now that Apple is planning to launch a Retina MacBook Air. The current MacBook Air line-up doesn't include any Retina models, but the latest speculation says that the new model with the higher-resolution screen will have a 12in display, rather than the current 11in and 13in displays.

Apple updated its MacBook Air line-up in April, giving every model a processor boost and price drop, so we're expecting a new Retina model to arrive towards the end of the year.

Apple rumours 2014: new Retina MacBook Pro

Apple didn't use last year's WWDC to update its Retina MacBook Pro line-up, instead waiting until October during the iPad Air launch to introduce new models, so we had thought that an October refresh of the high-resolution laptops was likely. However, in July, Apple decided to give its MacBook Pro line-up a minor spec boost and price drop, so new MacBook Pros in October seems less likely. Perhaps Apple is planning to wait until 2015 when Intel's next-generation Broadwell chips launch.

Apple rumours 2014: new iMacs

Apple launched a new, cheaper iMac in June, but did nothing but reduce the price for its other iMac models, including the 27in version. That's why we're still expecting to see new iMacs launch soon.

Apple rumours 2014: iWatch

The iWatch, which is what Apple watchers are calling the company's first (alleged) venture into the wearable technology market, is hot topic among the Apple rumour-mill. With the announcement of iOS 8 at WWDC 2014 came the news of a new 'Health' app, which we think would be a perfect fit for the iWatch and gives us a big clue to suggest one's coming.

Check out Apple's competition in our rivals to the iWatch round-up.

If Apple follows its usual iOS tradition, iOS 8 is likely to remain in beta form from until the 9 September event, meaning only developers will be able to use it. Therefore, we expect the iWatch to become available with iOS 8, which means a joint iPhone 6 and iWatch event is likely.

Apple rumours 2014: new Apple TV

It's been two years since Apple released a proper update for the Apple TV, and honestly, we're growing a little impatient.

With rivals including Google, Amazon and Western Digital releasing competing products that are pretty impressive, we're hoping that Apple has got something amazing up its sleeve for the Apple TV, and that it's going to show it off really soon.

The new Apple TV could have a microphone built-in, in order to enable the use of Siri with the set-top box. Code spotted in iOS 7.1.1 files indicate that Siri could be on its way to the Apple TV soon.

There are lots more rumours about the Apple TV in our Apple TV rumour round-up.

Apple rumours 2014: New Mac mini

We're growing impatient about the Mac mini too.

Mac mini fans have been waiting in the dark since October 2012 for a new update to the Mac mini, so we're hoping that this year will bring us an update. Despite speculation that Apple might be planning to discontinue the Mac mini, we don't think the company should ignore it.

There's been talk of a new Mac mini since late last year, so a new version in 2014 is certainly possible.
