Yeah, I'm taking this with a huge grain of salt, because according to Snakas's post here, these images are just Character Introductions (i.e. "Let's compare more DotM characters with their G1 namesakes!") -- and NOT necessarily indicative of upcoming products.

It's only been on Western fan sites that rumours of a reissue Shockwave has emerged based on seeing these images and possibly not reading the text that explains what they're about. Having not seen the box or inserts for myself, I can't tell directly, but snakas doesn't state that this is indicative of any upcoming releases and says that rumours about a reissue Shockwave have been coming from Western fan sites... certainly not from him.

I think it's best to follow 5FDP's lead and hold onto our horses until we see more official confirmation.
