If that's what they're doing, that is. Socialtext's site has no announcement about a December 1st press conference anywhere on their blog, and Mayfield's "announcement" of the conference includes more than a few jokes-- no ninjas allowed, "questions will only be taken from journalists in PVP mode," and a link to Project Azeroth (for those Hordies who might be a little confused by all the Common going around). I'm not quite convinced this is a serious commercial entry into Azeroth-- it could just be a dig at companies like Dell who "hold press conferences" in communities like Second Life without actually incorporating the community they're entering. The guys at We Know, umm, "know" Warcraft, and it could be they're suggesting holding a press conference isn't possible (especially not in Stormwind-- you should hold it somewhere fun like on a run through Deadmines, guys).
But you never know-- the only way to be sure will be to log into Eitrigg on December 1st and see what you can find in Goldshire. Mayfield's announcement does promise "those that survive the experience will gain 1 gold piece and a Socialtext tabard" (whatever that is), so it could be a money-making opportunity for both parties, in the real and the virtual world.
