Today's leak of the Huawei Watch on Amazon referenced the fact that the device was compatible with "iOS 8.2 or higher." Normally, it might be easy to chalk up such a thing to an oversight or automatic field-fill on the merchant page.
But I'd take stock in that information: we've learned from a second, reliable source off the record that Android Wear will be receiving iOS support soon. How soon? It's possible we could see an announcement some time around IFA, which happens Sept. 4-9, though the announcement may not necessarily be at the show or even during it - it's not exactly clear. But next month, generally speaking, sounds like a good bet for an announcement timeframe.
Android Wear support for iOS has been rumored for some time now. It seems as though the Apple Watch will be getting a bit of competition on its home turf soon - something I'm surprised Apple, in its infinite wisdom, will be allowing into the shiny aluminum walls of the App Store.
