So do you guys think that we'll have to wait for the official iOS 8 launch on 9/17 for these (Swype, SwiftKey, etc.), or might the Apple Gods magically bequeath a surprise of availability one of these days?
Apple will be allowing iOS8 specific apps right before iOS8 hits the streets and developers have been working on iOS8 apps, so I'd say some keyboards will be available when iOS8 is released and others will be available shortly.
I saw on twitter that Fleksy keyboard submitted it's app. So if Apple pulls a blunder or simply allows these apps to update before the 17th, the developers are certainly ready to make that happen.
