And on top of that, the "panel" stage is also bare. Last year, if they had a super populare presentation, they would do it on the main stage and another panel stage. Guys, if they are showing LofV off, its probably going to be during the SC exibition like Papaz said. Its just not THAT popular to tie up that much space/time (sorry). I also think that the timing of the Titan cancelation is very ... timely. I think they wanted to kill off all expectations of Titan so that it wouldn't impact the reveal of something new. Guys, I think we are going to see a new game at Blizzcon this year.
I think it's Overwatch. Blizzard would've said they'd canceled it if it had something to do with Titan.
