Usually around every blizzcon there is a promotion on every old Blizzard title (correct me if I'm wrong). So we are expecting titles like SC2, HOTS, D3, RoS, WoD, Vanilla pack and etc to go on some 50-75% promotion. Does anyone recall when that actually happens? Was it around 10 days before Blizzcon or did it start at Blizzcon?
Thanks.
