@PSRock: Their multiplatform strategy is supporting multiple platforms, as opposed to, say, Naughty Dog or Bungie, who are only supporting one.

lost odyssey is awesome and best this gen hands down.
i think ff14 will head to the 360 , but verus 13 will stay only on ps3.

those exclusives are "paid" exclusives.
microsoft paid of infinity undiscovery. so they own the IP, star ocean was made using a infinity undiscovery engine even though its multiplaform engine microsoft probably make sure it's not ported.
and last remnant use epic unreal engine 3 which til UT3 wasn't running well on the ps3 but there haven't still deny they are still working on it. since "It is intended by Square Enix president Yōichi Wada to "become a cornerstone for [their] worldwide strategy"."
their main multiplatform title.
