We have designed and scaled this item to fit perfectly with the G1 fans. The size of the Spike prototype is about 7-8 cm. We are currently working on finding the exact size we feel will be in line with the G1 toys. It also has wheels that will allow it to function and roll in alt mode. The item will be set for release late 2008 or sooner.
William also answered the scale question for us regarding the TFA figures – Sari, Captain Fanzone, and Prof. Sumdac.
With regards to the TFA figures they will also be around 8 cm in size. As in the cartoon the toys seem to change scale a lot of the time, so we tried to come up with a size that will work with the deluxe and voyager class as that is what scale we think most of the toys will be released in.
