Looks like he has a pretty big amount of nerfs. Just a few things I noticed...
*seems like rocket punch has too much start-up to do from a ground combo but we'll have to see.
*doesn't appear to have any super armor
*fly seems nerfed, i'd be willing to bet that you can't fly and unfly then fly again in the same jump
*mini sentinels appear to be pretty slow
*overall movement is really slow
he still looks to hit fairly hard, though. his air combos were overall underwhelming damage wise but some of his ground shit looked pretty strong.
edit: rewatching his speed doesn't seem to bad, and his stamina looks pretty good. chip damage on the mini-sents looks okay. with the slowness of rocket punch and the mouth laser not knocking down, I bet he is going to have a tough time getting in on opponents.
