Considering the $50m was a loan, it's very possible they've already been paid it back.
Not to mention the licensing fee for each copy of GTA4 sold on the 360 that Microsoft have gained
Plus the console sales they have got from people buying a 360 for GTA4
Plus the profit from games new owners have bought after getting a 360 for GTA4.
Even if MS did flat out pay for half the development costs of GTA4, they would have already made their money back and now will be pure profit.
Never argue with idiots
They bring you down to their level and then beat you with experience
