I'm not sure how they're going to do it "not on the clock", as it were. The time was such an important factor of Dead Rising. You had to save people quickly, you had to get the cases done in time, you had to make it all the way across the mall, which was full of zombies, and do it in under 5 minutes.... I'm trying to picture the game without that impetus and I'm not sure I like it as much. Also, the big drive of Dead Rising was the hundreds and hundreds of zombies onscreen at a given time. I wonder how well that'll carry over on the Wii.
That said, the motion controls could be awesome if done right, and shooting guns should be much easier now.
