Divinity: Original Sin is supposed to release in 2013 (Q3 for sure going by the forum). Dragon Commander is on track for May/June 2013 from the latest news, but it's more of a strategy game than a RPG. Both from Larian.

Elder Scrolls Online and Neverwinter are also supposed to come out in 2013. Both are "MMORPG".

There is also BG2:EE and Chaos Chronicles.

Plus all the Kickstarters that missed their end of year 2012 date and those supposed to release in 2013. I have 2 kickstarters so far that pushed back to 2013.
