Sadly doesn't sound like they are doing much more than prettying them up abit.  I was kinda hoping they'd tweak the original game some, fix the issues they had with Otis and dealing with survivors.  Oh well, I'll still at least pick that up.  I own 2 and Off the Record on PC already and don't expect too much of a difference there, but Dead Rising 1 I haven't played in years, so I'll grab that at least.
