The only thing I really want is for Apple to resurrect the live stream of these events. They did it for the "Back To the Mac" and "iPad2" events, then stopped (though live streaming the WWDC keynote, since it wasn't tied to any hardware announcements was probably wise...).
Sifting through the liveblogs is it's own kind of fun, but a live stream would be even better.
I have a feeling this is going to be a good one.
The problem with live streams is that journalists and other kind of invitees don't go to the events, and Apple, as any other company, wants to see their room full after all the effort of creating such an event like this. So, sorry, I would like to see a live streaming too, but knowing the pain it is make this kind of shows I understand them.
