I got the impression that the model data / textures will be pulled from the original game install. (If that's what you're alluding to). So if you've uninstalled it you will probably find a savegame file isn't enough to alow PT characters to be imported to the OT game. But console players will be able to import the characters as well. So it can't be ripping assests from the first game. The new one must have them all there, and they're unlocked by the savegame from the first.
