The Riddler will be released soon from Moebius. This will make the fifth entry into the Moebius Batman 1966 series. The manufacturer's suggested retail price (MSRP) will be $35.00 (I'm sure Animated Hobbies will charge less than that). Look for it to be released by the end of June, if not sooner.
Christopher Franchi has again done the illustrations for the box art. One more thing, all of those question marks are decals which come supplied with the kit.
