That's nothing compared to the Half-Life episodes. Episode 3 was originally planned for release in early 2006. Valve time is ridiculous.
Ya inorite? It nearly gave me a heart attack when I heard Portal 2 was gonna be postponed. I was thinking "Uh oh, here we go again..."
But seriously, that Meat ninja thing gets me thinking... I don't think that's in any way planned, but it would be hella tight.
