The text in those hidden file has been there since last year. This is nothing new for Apple - they put those model identifiers in the software, even when they know an update could be a year or more off. It's a placeholder.

That being said, we MIGHT see an iMac update in late September or October, but it will likely just be a processor/video card bump and possibly an SSD/storage increase if it happens at all. A totally new iMac probably won't happen until next year, along with new MacPros.

I'm also waiting on new iMacs. It's driving me crazy, because my 2006 MacPro is beginning to act-up (video card just died, and now other motherboard issues beginning to pop-up).
