I just came back from the event in Stamford, CT. They gave each attendee a copy of "Windows Vista Ultimate 32-bit SP1". It is a full version but not for resale. (Promotional Copy) All you have to do is use the pin inside of the Kit to register for Windows Vista Ultimate Product Key at "www.registerwindowsvistasp1.com".
Have Fun!!!
People attended the event in Phoenix on 9/25/08 did get "Windows Vista Ultimate 32-bit SP1". -Thanks to RebateMonger for confirmation.

Everybody in the room gets the Vista. They hand it out to the line of people exiting the room when the meeting is over. I've been attending these Microsoft events for five years now. That's how they've always worked and that's how they worked yesterday in Phoenix.
I have seen non-registered people just show up in the last event I attended and registered for spots on site. In case the event near you has been fully registered, show up anyway and register on site. -Thanks to cnIsfg for confirmation.

Show up anyway and register on site. I have yet to see MS fail to offer event day on-site registration even when the event was way overbooked. Some registered participants simply don't show up after registering for various reasons. We always have non-registered employees from our office tag along with those registered and they never had a problem getting into the MS events. Absolute worst case is that they turn you away and still give you the software up front for your time.
Added by SlamDonkey: you can use the 32 bit installation serial number with 64 bit media.
Added by Collije [11/3/08]: Also, you need to activate/receive your Product ID # by the end of the year (2008), per the MS Reps.
