Patch 3.1.1 for World of Warcraft is coming this week, and it's gonna be just a minor bugfix patch. But to address the problem with the dual talent specialization system, players will have their talent points reset.

Official Patch notes for 3.1.1

General

• In order to address issues with the dual talent specialization system, all players will have their talents points refunded. Players who have purchased dual talent specializations will have both specializations reset. Glyphs will not be affected by this reset.

Bugs

• Characters who are not of the same race or class are once again able to view each others' professions linked in chat.
• Fixed an issue in which player and pet nameplates were appearing larger than normal.
• Thrall’;s throne has been adjusted back to its proper size and the base replaced. He will no longer need to defy gravity.
• Fixed an issue with a display error on druid leather helms.
