A piece of news that I would have posted back when it broke were the site not also broke at the time, is that along with the Gocky Club 22 there is also going to be a Gotoh illustrated dakimakura (body/hugging pillow, link somewhat NSFW) cover on sale at the Summer Comiket (Comike 74 in August) featuring Akasaka Mitsuki, a character from the game Double Cast for which he was the character designer. I have not use for it, but I'll probably end up getting one anyway when I'm sourcing the doujin from Yahoo Auctions (hopefully from the same seller to save postage).
--edit--
And if I'd just waited a day.. the Gocky Club site has been updated again with more information and larger pics (now even more NSFW). There look to be two different versions; the one on sale at the comiket is 9cm × 24cm (price to be determined) and the other one, priced 16800 yen, is 50cm × 160cm and has blood which the other one doesn't, but I'm not sure how it is to be made available.
