The only thing that makes me slightly upset about this update is the fact that the Wario Chopper is a move. I was really hoping for a return of the original SSB stage entrances, and I figured that maybe the inclusion of Wario's motorcycle in the first trailer signified the return of said entrances, but the Hog's use as a move kind of makes that seem unlikely. Oh well, having it as such a unique move is so much cooler than having it just used as a character entrance, even though there is still possibility that the stage entrances will return anyway (I do not know why I think that if something is a move that it cannot be an entrance as well).
I also liked this update because it inched more towards ZSS being a transformation of Samus, at least in my opinion.
This update does leave a few interesting questions open though. The first one that comes to my mind is what would happen if there are multiple Warios in a match? Does each Wario get his own chopper, or do they have to share one? Second, since it looks like Mario is carrying Wario's Chopper, does that mean that it can be considered an item when Wario is not on it? Would that not make Wario banned from tournaments for the mere fact that he introduces an item into the match (by the way, I cannot stand the currently used tournament rules for anyone who would like to know)? Lastly, will Wario's FSA still be the big nuke fart, seeing as how everyone was lead to believe that it was called the Wario Waft, yet it now appears that the name is for a regular special move.
