Sorry, I just had to answer before closing it. No there will not be a dragonrush anymore or a button combo. Now all you have to do is press L2 and I think two other buttons (might very for different characters) to do a move. If you want more info on the next game PLEASE DO NOT POST HERE. THERE IS A WHOLE FORUM DEDICATED TO IT. BUDOKAI TENKAICHI. Now Closed Again.
