So, I'm already on the lookout for some products that are set to be released at Gen Con Indy 2007.

Castle Whiterock from Goodman Games. It's a 500-page boxed set for their Dungeon Crawl Classics line. That's about all we know about it, but what more do you need?
I was interested in Necromancer Games' City of Brass boxed set, but it's totally not at the top of my list anymore after Castle Whiterock was announced.
