You know the funny thing is we haven't seen Spock or Eraser since the announcement.
They are in a catatonic state from the shock.
Guys, its probably a good idea to assume the worst for the battle system... without AM2 what hope is there for a battle system as good as Shenmue 2.
I would hope that the groundwork is there for them to build on. It doesn't need to be as deep as VF, even the old games were like VF-Lite. As long as it's designed aroudn the P,K,Throw, Dodge mechanics like the last game and had the similar inputs it should be okay.
I just don't want them to turn it into Batman. The Batman system is fun for going for high scores and works for those games, but I don't want Shenmue to have it.
