To be honest I didn't expect them either. I posted the quoted text below on 9 November before I was aware of Black Friday. Taking that into account and acknowledging that Mondays are not normally launch days as this means web sites are being updated in the weekend (
), then Tuesday 27 would be the earliest likely date.

Move another week further on and you are either on 23 November or into the week commending 26 November, which is course is the last possible week if Apple is to make good on its November commitment.
As for the 27" models, they could follow one or two weeks later, so w/c 3 or 10 December. Any later than 14 December and punters will have their minds focused on other things as Christmas approaches...
Of course, all of this is total speculation...
The reason I'm reposting the above text is because I think Apple's decision to launch towards the end of the stated month is partly driven by the desire to have a reasonable level of stocks available, but also by the sensible plan to separate out the different events as far as the stores are concerned.
