The Apple Store was down on Wednesday morning, suggesting that Apple could be gearing up to launch its new Mac operating system, Mountain Lion.

The gold master of Mac OS X 10.8 Mountain Lion is already available to developers, meaning that the public launch is imminent. Most reports have been pointing to a 25 July launch, the day after the company’s financial earnings announcement is set to take place.

But this morning’s “We’ll be back” notice on Apple Stores worldwide could mean that Mountain Lion will be made available to download today, or perhaps the company is preparing for the new OS X’s arrival.

[UPDATE: Looks like Apple's six-hour downtime was to introduce a new text message order status update service for US customers.]

Interestingly, the ‘We’ll be back’ sign, which has recently replaced the famous yellow sticky, now alternates between various languages. It’s quite entertaining.

We’ll keep you updated with any changes.

What do you think Apple is up to?
