The upcoming WS08 launch event has a teaser here: http://www.microsoft.com/heroeshappenhere/cool-stuff/default.mspx that promises a virtual launch event (click on virtual launch experience), complete with "virtual backpack" that'll allow you to "collect the content you want to keep".

Imagine the trees that'll be saved... this launch looks like it might have the lowest carbon footprint Microsoft has ever thrown.

The "host" looks like she might be related to Ms. Dewey...
