I just finished the single player campaign mode of Gears of War 3 (GoW3) and felt that it was a lot like playing Gears of War 2. With the addition of a few new weapons, enemies etc, there isn't that much change at all but then again I have yet to play online against my fellow gears. I played a lot of GoW2 online (I would be level 100 if I didn't get fooled into a hacked game which reset my score) so I have some street cred to compare the two games :).
