WE ARE NOW 100% SURE, THIS WAS AN APRIL FOOLS' JOKE (GNOME's, not ours)!!!
As we all have witnessed, Gnome 3 was almost ready for release (the developers have created in the recent past weeks GNOME 3 images in order to be tested by the users and, of course, the important feedback be gathered), but, just now, on April 1st at the GNOME Release Team from Bangalore, India, a shocking decision has been taken--> GNOME 3 release is delayed until September 2011.
