Then again do people really want a new Dead Rising? The series is good as a trilogy (with 4 acting as a shitty non canon epilogue). Unless they do some serious changes, whats the point? They kept removing featurees more and more and thinking that adding shitty combo weapons would justify.
I think there's still potential if they focus closely on recapturing what the first game was like, bring back features they removed and trying to recapture the tone of the first game.
A new game like the first one but bigger in scale, I see a lot of potential in that.
