So this is what it has come to. Microsoft could be running into this shit storm with every major multiplat release if they're not careful. Obviously if this rumor is true, the third parties don't care about the graphical discrepancy, and will pay the PS4 its due in resolution, even if it is to MS detriment. Hoh boy.
If this becomes a common theme, MS might have to try and moneyhat the third parties into keeping their games at parity. I know that sounds crazy but what other choice do they have? If the public catches on to this, it won't matter how many friends someone has on Xbox Live, they will make the jump and tell their mates to make it with them.
Significant price discrepancy + noticeable difference in visuals = very bad news for Microsoft.
