To be honest with you guys, this version of Dead Rising actually looks like more fun. Maybe it was just me, but I thought the original was a pretty damn mediocre game.
In this version, they dropped picture taking since it was useless anyway in the last game, they reduced the zombie count (too many were on the screen in the last one anyway) and they axed the jumping. While this exclusion is disappointing, realistically, it won't alter gameplay in the least.
On the other hand, they made the entire game more linear, which should make the game more fun and interesting since, in the original, all of the side quests got really overwhelming and annoying, and they added Wii pointer support, RE style.
I predict this game will also be mediocre, but I'm guessing it should actually be more fun to play on the whole than the last one. The entire allure of grab lots of **** and kill lots of zombies dies in about an hour or two anyway, so given the core of the game is more focused now, I'm guessing the overall experience will be better.
