That you have yet another multiplatform game? Not really. The PS3 has a lineup of Final Fantasy XIII Versus, God of War III, White Knight Story, Valkyria Chronicles, Disgaea 3, Resistance 2, BlazBlue, LittleBigPlanet, Infamous, Team ICO game, a new SMT game among many other titles.
Meanwhile, all the 360 has going for it are games I can play elsewhere. FFXIII included.
