I was actually about to make a post about this. So far I think he has been in the biggest disappointment in the game. He has 0 customizablity, save for unlocking his crap, which is annoying. Hopefully one day they will allow you to actually make your own fighter.
As for any other disappointments, the super-unlockable theory is still up in the air. I have a hard time believeing that Liu Kang and Raiden are the super's simply because they are both pretty easy to get, and RAIDEN IS ON AN XBOX COVER. I think the supers will just be the characters from DA, since they still have their game graphics and full move sets. Who knows. Time will tell.

I think they took out his customability because he would be so cheap to use online. No One would pick any other character. Just give him all the best special moves and fighting styles and it's game over. I think it was wise for Midway to get rid of this feature. Or maybe just make it a single player feature. It would also take away from the unique persona of every other character.
