Wrong board, but no, the current $400 model does not play anything but PS3 games.

Next month when Metal Gear Solid 4 comes out they will be bringing back the 80GB PS3 which does have a good deal of backwards compatibility. I don't know if they'll be releasing that PS3 on its own or if it's just in bundles with MGS4 though.

Also, FF13 has been 'announced' for some time. I think you'll be waiting a while for it though.
