They're supposed to have added ratchets to the hip joints.... which is fine and all, but I want to know if they made the various arm joints tighter, got rid of the diecast in the fore-arms, fixed the little problem with the hands crumbling, fixed the lousy shoulder joint which tended to fall apart, fixed the gimpy leg-lock-out, fixed the landing gears that didn't deploy correctly, made it easier to transform into fighter mode and fixed the wierd upward pointing nose.
If they fixed those issues, I'll one.
