This update covers “only” 9TB of data, but they brag that it covers over 1 million square kilometers of Earth. That sounds nice, but I wonder how it compares to previous releases and typical Google Earth releases? I have no idea. I have a feeling that it’s a pretty low number, but it sounds good because we have no scale to measure it against.
In any case, it’s still a very nice update and covers more than 65 countries. You can get the full details on VE Evangelist’s blog.
