Same thing happens with Watch Dogs, COD, GTA, Battlefield, Titanfall, Assassins Creed, etc. and we don't know how much money changed hands.
It's unfortunate, but Microsoft, Sony, Activision, EA, Ubisoft, 2k, etc all partake in this nonsense. It just so happens that Destiny happens to be a Bungie game and probably one of the most, if not the most, anticipated games of the year, so people are now having their feelings hurt.
It's unfortunate that Sony outbid Microsoft on this game, but I guess with all the money Microsoft is spending on exclusive COD advertising and MP maps (which I don't give a **** about), this was bound to happen.
