Hoth Echo Base revealed at LEGO.com
At last! Details for the Hoth Rebel Base have emerged -- but only in German! The Star Wars page on the German LEGO.com site has photos and a description, but the set disappears if you change the site's locale to USA or UK.
If you can't read German, head over to Smashing Bricks for a translation. It looks as if it comes with 8 minifigs, no doubt some of which will be exclusives.
