I'm not fond of auto transformation.. unless it's going to be high quality metal gears and components inside to handle the stress and easily adjustable for those cases where the gears aren't meshed correctly and some part doesn't line up properly.
I'd much rather see fiber optic running lights, light up engine, a lit cityscape in the legs, posable guns and gun turrets, heavy duty joints for the shoulders and ARMDs with a pull/push lock system to hold the pose and not stress the joints . A metal frame for the arm assembly would be a must have for me to pose the arms without some sort of support. Frankly, I don't really trust Yamato when it comes to high strength plastic so unless it's some sort of nylon fiber reinforced plastic designed to handle the stress, I'd like to see the an internal metal frame from the shoulder mount all the way down to the arm where even the joints are comprised of metal. Stainless steel would be nice, not cheap brittle die-cast.
