Parallax Abstraction is right. Find me one PC game that didn't have some issues when launched. I mean, I understand there will be problems and I've had problems with many games I've bought on launch day. It's not that big of a deal, I can wait a week or so to play the game if the sound crackle bother me that much. It always kinda cracks me up how people say "they didn't test the game" or "this and that and my butt smells funny" on launch day. Games always have problems for some people, this is why there are patches. Just relax, it will all get fixed.
What is inexcusable is that guy from 2k saying people are on vacation. Give the guys some days off before launch, not on launch day. That's just bad management. You know damn well problems will come up and its best to have as many people as possible in the offices to fix problems asap or risk backlash.
