Speaking of Gen Con (as I did very recently both here and here), the forthcoming new edition of Dungeons & Dragons (D&D Next) will debut there. Pre-orders have opened for Ghosts of Dragonspear Castle, an exclusive D&D Next preview for Gen Con 2013 attendees.
According to game publisher Wizards of the Coast (a division of Hasbro), Ghosts of Dragonspear Castle is a "mini-campaign comprised of four thrilling adventures designed to advance characters from 1st level to 10th level. The book also contains everything a Dungeon Master needs to run the adventures, including D&D Next game rules developed during the massive public playtest, monster statistics, spell descriptions, magic item descriptions, and background information on the coastal town of Daggerford, where the campaign is based."
