I don't want to shit all over a game that I know nothing about yet, but if it is simply a port then I cannot see how this will turn out any good. Dead Rising is one of my favorite video games of all time, but I don't think it is really possible on hardware weaker than the 360 / PS3. The models are going to have to be extremely low in polygons and it is going to look like shit unless they drastically change the gameplay or reduce the number of zombies on screen. It just won't be the same game. It would be like porting Resident Evil 4 to the Nintendo DS or something.
What pisses me off most about this announcement is that it confirms that Capcom is legally able to make more Dead Rising games, but they are not making a sequel to the game on a system that is powerful to do it right. Sure they might be making one, but no one wants to hear about a damn Wii port. The millions of fans who bought the first one want a sequel, not a port to inferior hardware. Dead Rising and motion control might be kind of fun, but to make it a good game, they cannot simply port the game and massively downgrade the graphics and physics, etc...
Edit: I saw the scan and it looks like the subtitle might be "ゾンビのいけにえ" (Zombie Sacrifice / Zombie's Sacrifice) so it might not just be a port! Hopefully this will just be an original game in the series to tide fans over until a true sequel is released.
