I know the dodge chance calculation had been modified in RoS.
I've seen many Demon Hunters with 8000+ dexterity. The old formula will get >100% dodge chance which doesn't make sense. eg. A demon hunter has a dexterity of 8943. The battle.net profile page as of today (4/16/2014) still seems to use the old formula and shows this 109.43% dodge chance.

In game, it shows a correct dodge chance, but what's the new formula then?
BTW, the old formula in Diablo 3 is
if (Dexterity <= 100)
DodgeChance = Dexterity * 0.001;
else if (Dexterity <= 500)
DodgeChance = (Dexterity - 100) * 0.00025 + 0.1;
else if (Dexterity <= 1000)
DodgeChance = (Dexterity - 500) * 0.0002 + 0.2;
else if (Dexterity <= 8000)
DodgeChance = (Dexterity - 1000) * 0.0001 + 0.3;
else
DodgeChance = 1;
plus some skill dodge chance bonus.
