Site is there. Ticket, hotel promo links are found on there too. It will be held at the Planet Hollywood again slap bang in the centre of the strip.
Not many other details are the site until CCP start firming up the speakers and the like, but hey with vegas you really do go for the spacebros first, spacetalk second.
I'll be there too, and if I can come over from blighty, you all can attend in the US.
