FF7 remake on 360?

[-ku-]

Square own the IP, Sony part own the publishing rights with Square, in Japan, Sony in America, and Europe, Square International everywhere else and Edios on the PC. The only reason I could think that sony might own the IP would be if Enix sold that when they merged.
case closed square enix owns the game

Thank you for contacting SQUARE ENIX Customer Support,

We hope this letter answers your questions.

Square Enix holds the rights to the game Final Fantasy VII.

We hope this information has been of assistance.

So as we can see Square Holds IP Sony owns publishing rights in NA, EU and Eidos on PC.
So PS3 only might seem likely especially with ff13 sales being pretty good
