Kinda annoying that this line might be heading towards the path of a reboot, heard rumors of Megatron and Starscream 2.0 ..

A smaller Megatron to be in scale with Convoy .. I can agree to that
But what was wrong with Starscream that he needs to be re-done again.

Move onto new characters, like Shockwave and Soundwave who are in scale with Convoy v2, Grimlock, Starscream and Rodimus.
