News from GenCon indicates that the next core rule installment in the WH40kRP, the Rogue Trader book, is slated for the next GenCon in 2009! Interesting times, and something I look forward to immensely!
I’ll comment on the contents when details are released.
EDIT 09.44 CET: Having seen a picture of the poster that FFG are displaying at GenCon, we now have a link as well: www.roguetraderrpg.com. For now it redirects to the official WH40kRP forums, but presumably some info will get posted at the new page at one time or the other.
