As for app development, I see the point, but the .NET framework is built for quick development. The games might take longer because of the native coding and game engine stuff, but metro apps shouldn't be that tough. While that poses a risk on the apps that drop on release day, there should still be a good enough amount of time provided a big name app is finished through the x-mas season, no?
Not to mention, the big/notable developers have had access to the SDK for a while. It is the independent folks that don't have anything yet.
