Once they make it official and give it to the partners which I guess could be today or wednesday somebody is bound to leak it, there will be too many copies floating around by then.
There is no reason to hide something or delay the release. So I hope it will leak today. The question is if the build which OEMs/partners get today is also marked (to prevent leak) or not?
There is a keynote today and another on wednesday. I though I read they would like to announce it today with wednesday as the dropdead date. If the rumors are correct and 240 is the build and it was decided upon on friday then i would guess they will announce it today..we will see, another 4 hours.
