Improve the Warlock experience past 1.12?

Is there any plans to improve the Vanilla experience past 1.12? Like introduce some BC talents and such?
As you may know, one thing wich has been holding melee Warlocks with firestone back has been lack of an ability dual-wield. If warlocks could dual-wield daggers and swords, and firestones could be applied on a weapon instead of being held in the off-hand, the damage they deal with firestones would increase dramatically. If only Warlocks could learn dual-wield at level 20 from a trainer, this would solve alot of the problems that melee warlocks face. Consequently, it should actually also make the improved firestone talent somewhat useful.
