But again, Apple hasn't said that no new hardware will be unveiled, just that WWDC will be software focused. I don't think that is especially dispositive because WWDC is usually pretty software focused, with a product launch usually helping to anchor the event.
The rumors regarding the iPhone 5 have been so chaotic and random that I'm beginning to wonder just what can be established. There is a lot of credence to the idea that an iPhone 5 won't be out until September, but then that is counterweighted by rumors of it being no more than a minor update with a possible new camera and A5 chip.
At this point, I see three emerging possibilities:
1) The iPhone 5 does come out in June with moderate upgrades to the camera, storage, and A5, with iOS 5 coming out in September for all three products (iPod touch, iPad, and iPhone). This would seem to be supported by the fact that there hasn't been a software preview yet as there was in April for both iOS 3 and 4.
2) The iPhone 5 does come out in September (or later) with moderate upgrades and iOS 5 comes with it along with new iPods.
3) The iPhone 5 comes out in September with a much more substantial upgrade along with iOS 5 and new iPods.
The rumors seem to be pointing to #2 being the most likely at this point, but I have to ask the obvious question: is Apple arrogant enough (and it's customers blind enough) to sell 1.5 year-old technology at full price?
