Much appreciated for the more obsessive fanboyishness in all of us.
The vast majority of that is lifted from TvC. Right down to the basic attack combo being basically the X4/X5 attack with Zero switching his dominant hand, and even the double-bladed variety to the Hadangeki (incidentally, X5's saber wave was called Denharei, or likely Denha Zero with the way MvC3 is translating).
Aside from the obvious graphical changes, basically what was new to MvC3 was the Raikousen, the fact that Rekkoha is performed with the buster (the mechanics of the attack were obviously redone as well), and Genmurei. I gotta admit, that last one caught me by surprise. I thought it was supposed to be Rekkyoudan, from X8, especially since his debut trailer depicted it as a projectile reflector.
I'm surprised that they neglected to mention the fact that, despite it's name, Sogenmu's handling is more akin to Heat Haze, especially given that they chose Command Mission music for that segment in the video.
