Imagine this deal like golden handcuffs - Microsoft paying Rockstar Games a sackful of money to ensure that these two extra mission packs are only available (for the first year anyway) on the Xbox 360. Very interesting regarding digital distribution, institutional practices - not to mention a change in the relationship between PlayStation and Rockstar - remember that GTA was solely available on the PlayStation throughout the III trilogy: The trilogy of games that started with GTA III, followed by Vice City and San Andreas.
