While I'm sure that the new fancy 3D maps will look great, I'd much prefer they focused on updating their maps more regularly. I've looked at several 1,000,000+ cities recently that haven't been been updated since 2009, and in some parts 2007. I know some people will say thats only 3 or 4 years ago, but there are areas in those cities that have greatly transformed since then. They should work on making all major cities accurate to within 2 years before they start messing around with 3D.
Just going to point out Google does work with Cities to get map date. They buy it from a 3rd party. Chances that 3rd party does not have anything better.
