With Diablo 3 - once you beat Nightmare - you then end up with Inferno. That'll have a flat difficulty level (and rare drop rate) ACROSS the whole game! IE: If you want to farm whatever, you could farm any boss in Act 1, and you'll have the same chance to find that rare (and the same level of difficulty) as if you were farming a boss in Act 4!
