UPDATE: Apple announced the new Haswell iMac on 24 September, read about the New Apple iMac price and availability.
Apple could be planning to launch new Haswell-powered iMacs next month, with Haswell MacBook Pro with Retina display models expected to follow in September.
That's according to KGI Securities analyst Ming-Chi Kuo, who has this week predicted that Apple will launch a new iMac powered by Intel's new Haswell chips in late August. He expects a Haswell Retina MacBook Pro lineup to follow closely behind, with a mid-September launch likely.
Apple's MacBook Air refresh, which was unveiled at WWDC in June, already features Intel's Haswell chips, so we expect Apple will want to update its other Mac products to bring them up to date. At present, the iMac and MacBook Pro models are powered by Intel's older Ivy Bridge processors.
While there has been no official word from Apple about new Mac products as yet, Kuo has a good track record when it comes to predicting Apple launches. He correctly predicted that Apple would launch a 13in Retina MacBook Pro and Ivy Bridge iMac last year, that it would ditch the 17in MacBook Pro and discontinue the MacBook, and also that it would launch a white iPod touch. He even predicted the production issues faced by Apple when it launched the new iMac late last year.
Kuo has also this week predicted that the iPhone 5S is experiencing production issues that could delay its launch, while the rumoured 'iPhone Lite' is on track for a September launch.
