I would also add something about attempts to have greater collaboration globally, you only have to look at the investment put into the UNGGIM meeting in Korea and the Eye on Earth Summit in Abu Dhabi. Hopefully something useful will pan out from the various Network of Networks initiatives and we can share information and knowledge more readily.

The other area I would say is increasing significantly is open standards. Not just because I work for the OGC and it's my job, but because of the open government initiatives and also to some extent the open source drive as well (big community that works extensively with open standards).

Finally, regarding 3D there is a fabulous effort underway in the Netherlands as part of a pilot on the 3D standard for the Dutch Spatial Data Infrastructure. After an assessment of best practice they chose the OGC CityGML standard as the basis to develop this project.
