I haven't seen ANY bugs that cannot be fixed in a week. I don't understand why people assume it takes massive amounts of time to fix a bug. It doesn't. As soon as what causing it is found, it's often fixed by changing a few lines of code and testing if it works.
There are no gamebreaking bugs at the moment, I don't understand why people claim it's buggy as hell - it's not. It's just a wee bit unpolished - which is the exact reason it got delayed for 2 weeks. The week they have left is enough to iron out and smoothen it up for release I think. I don't think they even can delay it again, but if they do, it's most likely a week or 2 max.
