Oh yeah, 15 May 2012!
Torchlight will be released "after" D3 it seems, so they won't be too likely to get a lot of sales. They had their chance, but alas that ship has sailed.
I know what I'll be spending a lot of time on this year at least ^_^
If you are in Europe, check here for the cheapest prices. About 45e, compared to the 59.99 that blizzard wants you to pay. Don't get ripped off!
On another note DrakenSang is already available. And it's free to play.
Sadly that does mean you'll be thrown to death with "buy stuff" reminders in-game, but heck. FREE!
Basically it's an improved Diablo 2 clone. Or something that "tries" to imitate some of the ideas blizzard has shown for Diablo 3. The game runs in the browser, and has a fullscreen ability. Give it a try, if anything it's just a few wasted hours.
