Also I noticed my Home in Delhi has got an even higher resolution! And generally the images are brighter and definitely newer! Enjoy Google Earth!
Cities upgraded: chandigarh, bhopal, Indore, Ahmedabad, Vadodara, near Surat, near Nasik, Bhavnagar, a bit of Kolkata, and many patches in Gujarat.
There are more, I haven't seen all. Anyways if your city is not in high-res don't worry, coz even smaller towns have got a better resolution now!
Another significant change is that the global resolution i.e images for other parts of the world are now improved to 15 metres per pixel. Earlier it was 1Km/pixel. Which means even if your city is not in high-res you can still see buildings and all.
Man I need to buy a faster internet connection now!
