Sony is disappointed, but unsurprised, by the FFXIII announcement

At a
conference with game writers at E3, SCEA boss Jack Tretton spoke about Sony's feelings toward the announcement that a flagship title,
Final Fantasy XIII, will also see a simultaneous release on the Xbox 360. His feelings: "Am I disappointed by it? Yes ... Am I surprised? No." We suppose we shouldn't be too surprised either. With the cost of game development growing as it is, holding onto third-party franchises is much more difficult. The game is still PS3-only in Japan, but we should really expect this generation to revolve around first-party developers. Everything else will more likely than not see release on more than one platform.
