For those interested in the U.S. Northwest, I just noticed new Google Earth imagery for the Oregon area that was just shot in August and it is AMAZING! How far it extends I don't know yet....

I noticed quite a few updates over the last 6-months or so. Great stuff for sure!

NASA has also released new topography data with 15 - 90m resolution:

The data is available to the public.

Parts of Colorado imagery were also updated to August 2011 data.
I can now even see every single tie!
