Botcon Panel Notes: From Drawing Board To Toy

Earlier today there was a panel showing various prototypes, hard copies, conceptual art, etc for toys from the G1 line.  Some showed the Diaclone concepts and prototypes and how they changed from then to the eventual G1 toy.  Of perhaps the greatest interest was conceptual art for planned but cancelled additions to Japan's standalone Headmasters.  Although no pictures were allowed at the panel (which was completely ignored by a few morons who kept trying anyway.  Thanks a lot for trying to ruin it for everyone!) we made a list of what was shown, for those interested.  Most of these images will be online later this year at

Please note, this list was hurriedly made during the panel, so excuse any spelling or grammar mistakes.  It's hard to make this make a lot of sense without the images to go with it. Images will be showing up online, but no photography allowed – check
