I think Apple's position for iOS 6 is that they want third party developers to build the transit apps for wherever there's a need rather than trying to build in-house centrally managed support for the entire world. The new maps app will actually find an appropriate transit app for the requested destination installed or in the app store to hand you off to. For example here's one for NYC:
What this means is that for the next month or two coverage is going to be poor but getting towards mid next year they'll probably have better transit capability than Google. For example what I'd like to see is support for routing in my area using the real-time arrival data (our buses are frequently late), correct fare calculations, and balance info for my transit card. Google is unlikely to do any of this stuff but now someone who cares can go solve it. I think Apple pretty much botched the launch but in the not very long term it'll work out fine.
Myself? I'm holding off upgrading until a point release :)
