The first one out of the post-WWDC gate is Cantor Fitzgerald analyst Brian White, who has gone the extra mile to meet with supply chain vendors rather than just using basic reasoning skills. According to White:
iPhone in September. At this point, we're more surprised when info points to Apple releasing mobile hardware anytime of the year other than September/October.That is basically just about the longest trip you can make for a pretty easy guess, especially considering the iWatch will likely require an iPhone with iOS 8 to function, and iOS 8 isn't out until the fall. We didn't really need any supply chain info to guess that the iWatch is most likely coming this fall, just like we don't need the same supply chain info every year to tell us that Apple will release its new
That said, the guesswork on pricing is much more interesting in this case. Rumors about the iWatch pricing have varied wildly, but White is putting his estimate in the $200-230 range. That makes the iWatch far cheaper than many have been expecting, and it would price the iWatch significantly less than the Samsung Gear 2. That price range would make more sense if the iWatch is planned more as a health tracker than as a fashion accessory, as you might expect from Apple.
Anyway, we only have a few months left before real information could be coming. But, that does mean a few more months of the endless rumor mill.
