This certainly is a thing.

I have all three.

I hate two of them.

The third I have only a mild interest in getting as it looks really good. That being Shockwave.

Earthrise Megatron is a trash toy. Siege Megatron on the other hand is awesome. Nearly every single redone part sucks. That is quite the accomplishment to pull off. 

Ditto for Soundwave. Okay, I might hate on it a little more than I should. I do like Siege Soundwave and dislike Netflix Soundwave though. They didn't retool quite enough and well, I hate inanimate object alt modes. I'd rather have the space barge thing. Luckily I already have both versions so I can just use whichever one I want.

Shockwave looks good. But do I NEED another Shockwave? No, probably not.

At the very least this set proves to me that I was right buying a bunch of upgrades for all my Megatrons recently. Why? Because I don't think they'll be redoing him anytime soon which is sad as again, Earthrise Megatron sucks. Just make a good leader Megatron that turns into a tank. Galvatron and Armada Megatron came out great. Do that but with G1 Megatron now. There's been a rumor that a leader G1 Megatron will come out in Studio Series but I don't recall having seen or heard anything about it since. So it might be one of those that are indeed just a rumor.

Oh and I don't want another throne. 

Seriously if they only re-release soundwave in this pack people are gonna have a fit. I'm already pissed off just thinking about it.
