FF13 wont be out till 2009 at least, so if thats your selling point, you might as well wait cause the PS3 price will drop again in the next year. PS3 has a few good games out and has more coming down the pipe. Theres a lot of PS3 games that will be on XBOX and vice versa. Then again PS3 does have good exclusives. It has blu ray movies which are useless if you dont have an HDTV, which would compiment your 360 as well.
Wii is cheap and has games, and the unique control system and good exclusives. Id go with the Wii especially if all you are looking forward to is FF13.
Getting an XBOX One for me is like being in a bad relationship but staying together because we have kids. XBone we have 20000+ achievement points, 2+ years of XBL Gold and 20000+ MS points. I think its best we stay together if only for the MS points.
Nintendo Treehouse is what happens when a publisher is confident and proud of its games and doesn't need to show CGI lies for five minutes.
