Square Enix was basically trying to follow what Capcom did...They same can be applied to Namco Bandai.
Capcom is the only japanese publisher with tremedous success with the X360 platform...Pratically EVERY game they have released on that platform has sold over a million copies or more.
But the problem with SE following Capcom is that SE main product is JRPGS and in the west unless its Final Fantasy or Kingdom Hearts no one gives a shit...It pains me to say that because I love JRPGS but its the truth.
Capcom themselves said they aren't going to dabble in JRPGs anymore due to how poorly they preform in the west...That is the terrible irony here of SE following Capcom.
Capcom is the only japanese company that "gets it" they know the type of games the west likes and they cater to it really well...SE thinks they can put japanese centric games like JRPGs and expect them to sell big numbers just because its on X360...Its not that simple.
