I wonder who gets stage time today besides Tim?
Despite their claims of diversity you can bet that as is typical, all presenters will have a Y chromosome.
As for the issue of rushing etc, I truly believe that that is the answer to the riddle of the Great White Box. In the past couple of years they split things up and so they basically filled up the empty space with multiple demos.
This year I think that they will not do a second event, everything is coming to light today. Sure not all of it will hit the shelves in the next week or two but we'll know what's coming and the blogs etc will be creaming themselves with article after article from now until the end of the year, enjoying all those page hits and all that ad money.
The Demos will be what is lacking during the keynote, not announcements. Media will go over to 'the box' where they can demo things live, perhaps even being allowed to record their playtime to post on their sites.
