So... how does Early Access work with physical pre-orders?

Nope it will happen. Probably a few times over the first 2weeks, they'll have emergency maintenances. Cant test for everything, so the bugs will crop up as more people try to play. No matter how good Quality Assurance is, there's always something. All they can do is hope its not something insanely game breaking or critical. Though I doubt the game would be down for an entire week. Just maybe a day or 4-5hrs here and there.
