- They used new imagery from planes to do this, not the existing streetview imagery - I guess that means optical matching of the kind needed to do this (make a model from streetview imagery) is still a ways off.
- 3d maps has been done like this already (by bing and others), though this looks a better resolution.
- As someone who works with city spaces - can I use the 3d data? How can I download it or who do I have to pay?

Bing appears to be using a non-scalable approach for Bird's Eye view. E.g., Seattle downtown contains a few 3d buildings in a very confined area. It might even be manually modeled.
What Google has announced is impressive because it is automated and scalable. Small demos are great and all (e.g. C3) but qualitatively different from getting something like this deployed into the real world.
C3 is a "small demo"? C3's 3D maps have been deployed and are publicly usable and cover at least 25 metropolitan areas. Google may be catching up fast, but there is nothing shown in the video that C3 haven't done already.
