I think they should have released it as Gen2 Megatron instead of Armada Megatron... with the green/purple camo and purple helmet head.
It would be a shame to not have some non-Gen1 homage toys being done, but in this case, it doesn't fit the aesthetic of Armada Megatron like how Tets described above. (I love that type of tank the Armada Megatron used too.)
