He got some significant changes to him. Not a lot, but some would say he got "nerfed". But now, 6B on CH doesn't cause a bounce-back. Now it just causes a long stun to your opponent allowing to airdash in for a combo. Also now his drills can be cancelled with specials on block, not just on hit. Also he has a completely new distortion drive. He sends out a gigantic, rotating cloth fan that's a multi-hit move. I'm assuming the strength of it depends on your current drill level. That's all I noticed from playing 2.0 the 2 weeks I was in Japan back in Dec.
