If there are visual upgrades I would probably buy this at some point. After hearing you guys talk about the Prototype games I have wanted to play them for a while. I have them both on PC but I have to assume they feel pretty dated at this point.
Edit: if they didn't make some real upgrades this is a pretty shameful re-release now that backwards compatibility is a thing. Of course, they probably didn't know backwards compatibility was coming when they started this project. Kind of makes you wonder if they are considering a Prototype 3 though.
Looks like your best bet is to play your PC versions. The Xbox One release actually plays WORSE than the last-gen releases, with a lock at 30FPS. At least with the PC version you'll get 60, although it is worth noting that the PC port isn't spectacular, and even on my 960 I was getting dips every now and then, but nothing significant. At least it's not like the One where you're getting FPS in the teens..
