So this just got out. No one here seems to have noticed it yet. Source is MMO-Champion. 
 

its fake because the WoW TCG is already out. 

Interesting.  Curious on what Titan is.

Ridiculous.  If they release Diablo 3 in 2011, they won't be releasing their second expansion to it in 2015. 

WOW mobile? That means wow on my phone?

All the best rumors take about 4 years to really verify.

The time line looks fairly realistic to me. I guess titan is the new IP they've been hiring for

I really hope this is real. If D3 is only a year out I will be one happy camper.

Doubting MMO-Champion just like that is usually a mistake. "

Titan probably isn't the official name of the game. They don't normally refer to official names until announcement. StarCraft 2 was Medusa and Diablo III was Hydra as codenames. Titan will probably be the same.

What if this was a COD MMO?

Diablo III in Q3-Q4 2011 makes me just want to skip this coming Christmas and go right to next year's. 

Warcraft 4!

Wtf is SC2 Phoenix? Some unknown Starcraft 2 project?

World of Starcraft, GO!

Project Titan confirmed as being in existence.
