I played it at last years E3 and was really unimpressed. However, I gave the Japanese demo a try and now that I have the controls down, I really like it! Action is fast-paced and you do have to strategize your fighting a little or you'll get your butt kicked online. PROTIP - TUTORIAL SHOWS YOU SEVERAL MOVE YOU WILL NOT BE AWARE OF OTHERWISE. So do it.
The single player campaign was a good size for a demo. One "Black Story" match against the Baron and "White story" has a tutorial mission, bonus mission and another fight as well as a sort-of "open world" where you can just kill as many dudes as you'd like.
Multiplayer lets you choose from about 5-6 guys and only has one map, but I love the chaos and how there's so much shit going on outside of just fighting your opponents. Also, I love, love LOVE the end result that give you a ranks not just based on kill/death ratio, but how much damage you did or helped other teammates and such.
All of this with the options to make it in total English. If there's no announcement soon, I'm importing this baby after comic-con.
