you did a little investigative work ... i like it, i will go with june 2-6 as well.I don't think it's going to be between 9-13th.. look at the Moscone calendar.
"6/13/14 - 06/17/14 American Diabetes Association 74th Scientific Sessions Moscone North, South and West "
Apple use Moscone West - therefore it can't be 9-13th as there's another event starting on 13th. Not only that but surely there would be a couple of days between events to take down/put up all the boards etc.
The only dates it can be during June is 2nd (with 1st as setup day) - 6th. This also lines up with the leaked 'provisional' dates a few years back - and most of the dates have been correct since.
What do you guys think?
