Perfection. Simply, Perfection. No other words are needed to describe this figure. (His tank mode also looked much better in the video than on the concept art!)

I wish this ended up looking like that concept art as the alt modes of the concept art looks a hell of a lot like Transformers Animated season 4's Marauder Megatron.

As is, he looks a lot like RotF Megatron in tank mode and core class Bomb-Burst in jet mode.

Could be a photoshop of the full body test shot in the (maybe) right colors.

Well, that certainly looks like the artwork. It also looks like it's a HasTak design.

This was rumored to be a leader class if I recall correctly. Looks solid so far but there's really not much to go on here. Elbows look like they have more than a 90 degree bend. Shoulder and chest joints look like there could be some decent butterfly joints maybe. Thankfully the head doesn't look like that horrible artwork. Maybe it's just because the mouth is closed. Elbow and forearm area looks like it does something extra. Or maybe it's just for transformation.
