Players will be able to switch between two talent specializations. Players will have up to two talent specializations and will be able to switch between them, action bars and glyphs will also be switched accordingly. (hunters will also be able to switch between pets according to this post)

Last time we heard about it, swapping specs (going from A to B) will truly be free in towns and possibly during the prep phase of PvP. In an instance it may cost a nominal fee (think reagent level). We want you to be able to do it when you want to do it, but we also don't want to slow things down if everyone is constantly flipping spec from fight to fight. But if it's free in town, then obviously it can't be more of a burden out of town than just hearthing and being summoned back is or nobody will use the remote option. (Ghostcrawler on Dual-Spec)
