Bioshock was originally planned to be for 360, PS3, and PC. MS bought the exclusiveity. So no. the two cases are completely different.
Yes but that does not change that both are currently exclusitivity, and are unlikely to change (well MSg4 not so much FF 13 yes, and bioshock yes)
With regard to Call of Duty 4 having an ultra short single player campaign, I guess it may well have been due to the size limitations of DVD on the XBox 360, one of various limitations multi-platform game designers will have to take into consideration-Mike B
