I second this! Many fans, myself included, were unable to see them at Anime Expo and Japan Expo. From what I know, It has been six years since their last appearance at a convention outside of Japan. It would be a great opportunity for many fans to see CLAMP at Otakon one day. If they did attend Otakon, I suggest at least two autograph sessions and a panel. I understand that many fans were content with Japan Expo's two autograph sessions. Unlike the lottery system at Anime Expo where many fans were disappointed. Lottery systems can be cruel when luck is not on your side.
