Square's been looking to publish more western-friendly titles recently, e.g. publishing Supreme Commander 2, the announcement that FFXIII would come out on the 360 in the west, etc., so it's not terribly surprising. Though really I don't see it doing much for them unless Eidos' studios either put out a great new IP or really do something innovative with their current ones. They did a decent revamp of Tomb Raider but people are showing that they just don't care about Lara Croft that much anymore. Kane and Lynch was a bomb. They have some other fantastic IPs but they just don't really seem to want to work with them anymore - Hitman, Thief, etc.

I dunno, I don't see it being that great of a deal for Square. They get to push some new games through this, but not really anything I'd expect to sell particularly well.
