My gal and I are quite excited for this one! My concern is with using a PS3 gamepad on the PC. I don't suppose it has built-in support or an option to use the PS3 button prompts, does it? Using a keyboard and mouse doesn't fit well with sitting on the couch and playing it on the big screen, but she's not a big enough gamer to be able to see 360 buttons on screen and instantly know which buttons they map to on a PS3 controller.
And I don't have a wired 360 controller or the USB dongle for wireless ones, hence using a PS3 controller.
