As an iPhone developer (who occasionally gets requests for Android ports), my assessment is that the Android-revenue issue isn't going to change much in the short-term.
As for the total Android vs. iPhone sales numbers, I think two factors will play a significant role next year
(a) if the iPhone is available on Verizon, T-Mobile etc. they'll be able to overtake Android sales again (b) I realize that Microsoft is unpopular on HN, but imo Windows Phone 7 will take away more sales from Android than from the iPhone.
It seems like Windows Phone 7 should take away market share from Android, but there's one key problem that I think will prevent Windows Phone 7 from doing that: Internet Explorer.
IE is a resource hog, and has horrible standards support. Most mobile sites won't work with it unless Microsoft manages to get IE9 ready for production use with Windows Phone 7. From all the stories I've seen, they seem to think they can restrict users to using IE7 and still have a good mobile experience. The mobile web is Webkit, and I don't see IE standing a chance.
