I think it'll get 7.5 to 8. It's not going to blow people away but it is what it is. More ultimate alliance. If there was more upgrade paths and equipment it could have been diablo but I'll be happy with more of the same and a lot of extra DLC characters. Hopefully the DLC packs are at least 5 characters each.
Some strong rumors that at comic con they will announce a new charcters or two which is locked behind a day one patch. Even rumors it could be link or samus as they were supposed to be in X-Men legends but it never happened.
