So what. It just means you have to wait a little longer. If I have to wait another 6 months so that they can fix all the bugs or playtest the levels thoroughly to make sure they are fun, I'm all for it. I'd rather they take the time to do it right then push out a game riddled with bugs.
And I always see reviews that says "x company should have kept the game another 6 months and worked out the bugs" and "a great idea turned into a crappy game due to rushed deadlines". But when a company does keep it for another 6 months, everyone complains?
Look, we all want to play the game sooner, but it is in everyone's best interests (except hardware makers) for them to delay the game. It just means I'm gonna wait to do my dx10 system build a little longer, and hopefully a bunch of vista patches will be out by then anyway.
