They're rebuilding the game from the group up for console so I'm sure the controls will be fine. Behind all the semi justified complaints and nip picking Diablo 3 was a really good game. Console version will have none of the issues PC had. I've been playing on PC for awhile now also and its filled with a bunch of elitist, entitled gamers. D3 had its issues but it was magnified by the shrieking cries that only PC gamers posses, making it seem like Blizzard murdered their dogs.
Kind of like the whole ME3/EA situation, I just enjoyed the game for what it is while everybody else was crying about it.
