Power Morphicon, the first and currently only full-scale convention for the Power Rangers franchise, has apparently extended an invitation for the cast and crew of Kamen Rider Dragon Knight to sign autographs for what will undoubtedly be a crowd full of crossover Kamen Rider fans.
Steve Wang confirmed this via his Facebook account.
While none of this has been added to the convention's docket as of yet, it's impossible to say who will be showing up to the signing, and at what times the signings will be taking place. Also, chances of actual panels discussing the series seems unlikely, as Adness Entertainment (the producers of KRDK) has no official capacity at the event.
Power Morphicon will be held in Pasadena, California, August 27-29, 2010.
