So I've played and messed around with FFXIII and I'll give my quick analysis for those who are curious.
The launcher has two options. 1280x720 Full Screen or 1280x720 Windowed. Then once you launch the game there are no video options, just the usual stuff from the game originally along side the option to choose keyboard or controller prompts.
After getting in game, the videos are fine in the sense that they are the same resolution that you are locked at. Battles seem to be locked at 30FPS, as are the videos. This may be something that's only in the beginning. I'm not sure. Seems to run fine on my 7950, but frame rate does fluctuate a bit when I force AA/AS from my video card.
Oh and hitting the escape button completely kills the game. Game looks fine and plays fine otherwise.
tl;dr If you are looking to just play through the game, it should be fine (Provided you don't have issues running it). Those that are looking for the definitive PC version that you can trick out, I wouldn't count on it until someone manages to create a program to force some better options.
EDIT: I just realized I was forcing maxed out Anti-Aliasing and Anisotropic Filtering. That was causing the frame rate to change a bit. Turning it off, I was a constant 60FPS when the game allowed for it. So I fixed the wording.
EDIT 2: Fixed typo on the resolution.
