That is my understanding too. Part of the problem with the iOS 6 maps is just down to presentation, which they at least could fix. Though I fear that they won't, I think someone at Apple thinks maps with not a lot of info on them are somehow better than those with more info

On the data side I guess I'm holding out the hope that they can merge in some data from OSM or some other source. Bing is notable in that in the UK it uses NavTeq, but it clearly doesn't use just NavTeq (unless NavTeq have a lot of detail that TomTom choose not to surface in their own apps).

Or in th UK maybe they could do a deal to get the Ordnance Survey vector data.

But I suspect that is wishful thinking for version 1.0 at least.

And unfortunately even if they did manage to do all of that, there would still be no StreetView
