The moveset seems to be the same with small physics changes and possible power increases. That's not bad since as I mentioned earlier in this thread, Ike's moveset is pretty good but he was limited by some of Brawl's mechanics. We need to know if jab cancelling, combat walking, the combo potential of his throws and the likes of nair, and kill moves.
The trailer had Ike's jab3 nearly KO a group of opponents, but that could've been Smash Run, but I didn't like how aether was missing a lot in the few clips from the most recent demo build. I doubt that any of the demo players are too familiar with Ike, but I'm happy with what we heard. At least he doesn't appear to be nerfed and can be picked up easily for us who played with him in Brawl.
