If anyone is interested, Google has been gradually starting to add more countries in Eastern Europe to their StreetView feature. As with Western Europe and the United States, they are starting with the biggest cities and moving out from there.
It appears that they have already photographed parts of Romania, Ukraine & Russia and most of Latvia and Estonia.https://www.google.com/maps
To see the areas which StreetView is available, click and hold the yellow guy on the left of the map and drag him to the blue areas on the map. It will also show photographs as blue dots. The StreetView portions are indicated by solid blue regions on the map.
Apparently they've been photographing Greece since 2009 but they stopped temporarily since the Greek government wanted more information to protect the privacy of their citizens. Last year the government passed a law allowing the photography as long as the faces of its citizens are blurred. This is probably one reason Greece hasn't been added, since it would take quite some time to blur the photos of people on all of the streets.
