What happened to the loyalty?

At the end of Microsoft's E3 press conference it was revealed that Sony had lost yet another exclusive, Final Fantasy XIII. This caused quite a riot among Playstation fans. One comment we've seen goes far enough to call Square Enix traitors. A comment like that only shows blatant fanboy-ism and while there's no problem with being a fanboy, you have to look at the facts. Square Enix owes no loyalty to Sony, they are and have always been a third party developer. Microsoft probably coughed up a pretty penny to get such a high profile game onto their console.
