I'm a bit surprised with the lack of Diablo 3 commentary. But that's maybe because they're too busy playing the game.
IMO, it's much better balanced than D2 (as in no clearly useless skills, fewer completely useless item mods). My 2 cents on the next patch is that they shouldn't nerf IAS (it's not overpowered to the point that it's a "must have" over other good modifiers), and they shouldn't nerf act2 inferno. While it is ridiculously hard, that's kinda the whole point of inferno difficulty.
