That's a link to LEGO Club's US Event page.
Scroll down for an August surprise.

Yup, that's the first official listing of your new 2009 Space theme.
Yay! We can openly discuss it now (...right?), and we have an official name. All the sets are still just rumors, of course, but the theme is now quasi-official, which is heartening.
In related Space-y news, the LEGO Factory sets "Space Skulls" and "Star Justice" are now just $35 each on US S@H. Yowza! I don't even like Space and I'm thinking about picking up a few (y'know, 'cause they're really Factory...). The other recent Factory set, "Custom Car Garage," is on sale for $35 as well, so you can scoop them all up and take advantage of their "Brick Friday" weekend savings as well. Must...resist...impulse...purchase...
