Over at the official site they wrote the following message reguarding the big announcement.

“we’re gonna be on something BIG!!”

Scroll your mouse over the message on the official site it says “I’m on a boat”.

Also they updated the post about the big announcememt with the following.

Save the date December 9-13, 2010.

So that to me that means a cruise. If it says I’m on a boat. Makes sense. If you don’t see that message “I’m on a boat” then you’re probably on a mac. People seem to have a problem seeing it on mac. I made a screen cap here.
