Just thought I'd throw something out there. 13 hours ago, Pokemon's Facebook page made a post "Who's That Pokemon?" It's obviously Togepi. But! Why Togepi was my first question? Togepi is one of the most important Pokemon anime-wise. Misty carried it for ages, you saw its journey evolving, and then eventually becoming Togekiss. It's important. I haven't seen them post that sort of thing for months (I did a quick check back) and with nothing happening Sun and Moon-wise (everyone is concentrating on Pokken)... do you think that this could mean Togepi's line could possibly get a Mega Evolution in these games? Or is it just random? Honestly it's sort of in the middle of everything. Any content they should be posting would logically be related to Pokken given it just was internationally released. So what's up with that? Random or actually potentially related to the games?
I think it's coincidentally random, but I definitely would be happy to see a Mega Evolution for Togekiss happening if it's the case, because I want to see more new Megas in these games.
