the world is not enough
as long as Cologne/Germany is not in hi res, it's not a real update. ;-)
But all joking aside: I understand that this is a US product, but hey, it's called Google earth, not google US. In my opinion there's too much focus on the USA (even if I like to watch all the places I visited in North America). There are only a very few spots in Africa or in South America with high resolution.
@Mickey: is it because the authorisation from other countries is more complicated? Do you know anything about it? I think that hi res exists for every single inch of this planet...
