If they are able to get the UIKit framework up and running, then they will have the killer platform overall.
I can see already the advantages for games that are mostly OpenGL but with UIKit it will be 'game over' :-)
Suggestion: you may want to have somewhere a screencast showing a standard UIKit app demoed, may be the standard Widget catalog demo that's available with Apple SDK.
I assume and hope your upcoming announcement is regarding non-game apps. :)
