Screw DS and PSP. This is a 360 forum.
Yes I will be buying DOA 4, I loved 3, and personally its one of the best fighting games to me. Tekken doesn't wow me, Virtual fighter was eh, Soul Calibur is great but its almost like a different fighting genre with all the weapons, but still DOA 4 is just so fluid, interactive with the characters and the environment, and just has such a plethora of moves that I need this game.
Boobs don't hurt either.
