Theory about new megas

I have a theory that has little evidence, just one that I find enjoyable. It’s that Raichu will receive a mega evolution, whose design will be Gorochu’s. We’ll never receive it as an evolution due to Pichu’s existence, but I think this is a perfect way to incorporate it into the games.

Although Raichu isn’t one of the top Pokemon I’d like to receive a mega evolution, i would be undeniably happy if this were the case
