However, CEO's are supposedly the ones who let this slip, and ultimately what they say goes. Since the install base is questionable, I wouldn't be in the slightest bit surprised if they did want to multiplatform it. Also, as far as the size much of the blueray contains is uncompressed data for faster streaming, and since they dont use special hardward codex (360 has some strange hardware to allow VERY compressed vid/cutscenes) that wastes much space. Yeah, it'll save on data transfer times, but it also take ALOT of space.
