Sigh, okay.
None of the lists are "catalogues" of the new Mega Evolutions. None of them. Not the one with 6 Pokemon from each generation, not the one that listed various pre-confirmed ones with a few others thrown in, and especially not any of the anonymous 4ch ones. The trademark list is iffy at best, it's already missed some Mevos, and it likely is just a list of, you know, names that GF needs to trademark or re-trademark, for merchandising or otherwise. Any list that seems to be matching up partially is just pure luck; Togekiss, Yanmega, Salamence, Flygon, Chandelure, Scizor, Porygon-Z, Milotic, Tropius, Gliscor, Skarmory. I just pulled all those names right out of thin air, and since they're popular Pokemon, it's very highly likely that at least 1, or even more, of them will recieve Mevos. Throw in a couple that are already confirmed, and voila! You have a "list" of Mevos. Except you don't. If you throw out a large enough net, you're bound to catch at least a few fish, but you're not gonna haul up the entire ocean.
