SC2 is a mess right now they need to to focus on balancing the game as its broken right now and deal with the large amount of hacks running rampant on the ladder since the game went f2p before then even consider porting it anywhere.
No wonder BW is getting a third wind and new resurgence.
Hacks? That isn't happening mate. And the balance is fine, not the best but one of the best periods in sc2.
BW is only getting a resurgence in Korea, and it is such a different game you can't compare it to SC2.
