Yeah, they seem to have moved to a 1pm slot now. I preferred the 8am releases though, get up, get it ordered then go on with your day. Rather than it being in the middle of the day.
That said, it's felt like the past few launches haven't necessitated the mad 'i must get in within a few minutes or I'll miss it' of old though. Guess it depends each year and will be affected by model and finish, but I'm sure the 12 PM 512 silver i went for last year was still available for launch day for hours if not a day or so after pre orders went live.
