Well, I'd fall into the 'don't hold your breath' camp, but look at what happened with Starscream. It was rumoured last Christmas that Hasbro was going to come out with a version. What happened? I dropped full coinage on an MP11 and now we have a Hasbro SS.
The gun part of Shockwave will be of no consequence. I'm no expert but considering we don't have the same laws governing toy guns, importing a Meg 2.0 shouldn't be a problem either. Orange plug Megatron was a victim of the current overly PC environment we live in. We shift the responsibility of parenting over to big corporations and yet there's still no reduction in gun crimes; it's actually worse. That approach doesn't work: talk to your kids, that actually works. But it's work. People don't like work. Those people should think twice before procreating.
Wow, must be an election year, that was a non-partisan rant
