Wasteland 2 will be out next month. I helped Kickstart it & have been playing the beta & it's pretty damn good. It's being produced by inXile which is headed up by Brian Fargo (the guy who created the original Wasteland as well as Fallout & Fallout 2) & they are getting help from Obsidian Entertainment's Chris Avelonne (who also worked on Fallout 2 & whose resume reads like a PC gaming greatest hits list) Obsidian is also working on Pillars of Eternity which you may want to keep your eye on for the future.
Alternatively, Fallout: Tactics is also a great game after you patch it & apply the unofficial patches. May be a little light on the role-playing for you, but the tactical combat is bar none.
Finally, as Benny said, Divinity: Original Sin is an excellent tactical RPG, one of the best I've played in years. I beat it about two weeks ago & it was thoroughly enjoyable from start to finish.
P.S. If you haven't played Icewind Dale, Planescape: Torment or Icewind Dale II, you owe it to yourself to give those a shot.

"How is it that a lame man does not annoy us while a lame mind does? Because a lame man recognizes that we are walking straight, while a lame mind says that it is we who are limping." - Pascal
