Good overview by Andy Baio of the iOS 6 Maps transit situation — including how the APIs for this will work (at least right now).

It surprises me that Apple is going to go backwards in user experience but based on everything I have seen and read it appears that is what is happening.
Google maps is by far the most used and important app I have on the iPhone.
If I was Google I might not release a new map app for iOS, tell people to just go to Android, at this point I might.
