I think ps3 should definitely get this one. Mario will give the Wii a boost next week, but not near as much of a boost as ps3 will get with FFXIII. Various other Mario games are already out on the wii meaning a lot of the "Mario" fans have already bought a Wii. FFXIII is the first TRUE traditional jrpg for the PS3 other than WKC which was a new IP and Tales of Vesperia which was a port. FFXIII is going to sell a lot of consoles and keep the ps3 the "hot" item for some weeks. Star Ocean 4 also comes out for the ps3 early on in 2010, but I think the ps3 will reach 5 million well before then.
