Wasn't Y-P asked about early access length and he said not seven days, more like five... probably more like three. and then settled on 3-5 days? i think that was during the E3 letter?

Otherwise you're sounding accurate enough. Personally, I want to go to Gamescom, so I was kinda hoping that early access would be 18-22 and then servers would be taken down for that (22-25) where there would be some huge-ass launch party event with all the coffee and cigarettes you could drink.
