Google has just released new imagery for Google Earth (exit GE and re-load it if you had it turned on over night). Most of the UK is now in high resolution. It appears there are many new strips of Digital Globe satellite photography in many parts of the world.
There are many updates this time around, so be sure to load Google Earth up and see if your city had any special treatment. Going by reports, it seems Germany and the UK has had the best updates, although some parts of Antarctica are also now visible. Though, even with the highest resolution imagery available, there would not be much to look at down there.
