No. Blizzard confirmed that Titan is an entirely new IP.
Interesting, and is Titan an MMO?
I can see them going the scifi route, even if it isn't the Starcraft universe.
Maybe a Steampunk IP. WoW already has some characteristics of that with all the goblin stuff.
I just wonder how far out it is. They take forever on this stuff, but they are also super secretive about development. So it could be far along already. I would think releasing it somewhere around the 10 year mark for WoW would be a good idea.
Titan is the codename of the new MMO. Don't expect it to be released prior 2014 or 2015.
Allegedly, it's gonna be set in the not-too-distant-future, due to some clues that Blizzard is hiring an ingame-advertisement manager, where they can add Coca Cola ads and stuff. Wouldn't fit right into a fantasy game.
Plus it might be maybe F2P.
