Regardless of whether you think TL2 will suck or not, I think D3's new release date for Q1 of 2012 opens the door for TL2 to really build its community, assuming Torchlight 2 will still be released before the year's end.
Torchlight 2 has stated already that they're slated for a release before the end of 2011, which until a couple days ago, was in competition with Diablo 3's release. But I think D3's setback will now give TL2 the advantage of more people buying their game and investing time into it. Whereas before, I thought I would buy D3 and then maybe get TL2 on the side to see how it was, I'll have the opportunity to get TL2 first and play it in the meantime before D3's release.
What do you think? Did Blizzard just inadvertently throw TL2 a bone by pushing back their release date?
