Well, since they used a different term, being Ancient Devolution, there's no twist. They just aren't Megas period. Mega Pokemon specifically use a Mega Stone and have Mega in their name. They specifically use some kind of term to mean Ancient(or other similar words). They're more akin to a Forme Change by definition, I guess.
Not really, the twist could be in the name. The idea could essentially be "it's Mega Evolution, but devolving so it's different!" Similarly, we have not seen any indication of how these things are formed, so saying "well they don't have a stone" is completely haphazard as we don't even know how they're formed, much less if they hold an item.
I wasn't saying otherwise. I meant that the concept exist already, that's all. Returning to your first form in some way. That particular concept. The fusion concept and ancient devolution idea are still separate concepts, of course.
I still disagree with that, but apparently we're not budging, so lets move on.
They're still different overall. Ignoring the devolution point for a bit, the Ancient Digimon actually disappear. Kyurem is still there and didn't lose all of its power.
Not really, the thing is the Original Dragon is technically non-existant just like the Ancient Digimon are. Neither are physically present in the world where their lore takes place at the point in time we see the story, and like them, it has components present like Kyurem, but they're not the Original Dragon on their own. They form the whole, but none of them are the Original Dragon in and of themselves.
I'm thinking they're none of the above, and their own unique mechanic.
Potentially, but that's something we have to wait and see.
Not really. We knew Kyurem was split up very early on.
Yes, we knew that they split up, but we didn't know how they'd be formed. Before Black/White 2, we had no clue we'd have two forms for Kyurem, how they'd be formed, or even if we got two games. Similarly, GF never gave out how they obtained that form, we had no knowledge of the DNA Splicers until the release of the game.
So knowing that, GF will probably keep information about these two close to the chest until they feel ready to reveal them, if they even get around to it.
That's why I'm getting the impression it actually is a new form of "evolution". Who knows, there might be more in the future. Possibly for a lot of regular Legendaries or ones that existed for ages. Ancient Lugia and Ancient Ho-Oh could make sense. Mewtwo was created in a Lab, so it having an Ancient transformation wouldn't make much sense.
This is where we differ, we both agree that they're "evolutions" of sorts, but in what manner is where the difference lies. Personally, I feel that it's still going to play close to the Mega Evolution concept, whereas you, you think it's going to be completely different, and at best draw from Forme Changes.
Also, potentially yes, I could easily see them pull this mechanic for the other mascots (though maybe under a different name).
Correct, they didn't. It was treated as a form change(in practice) due to no Mega Stones existing in the movie. In the same sense how Aegislash can change forms on a whim. Another movie using Mega Mewtwo Y came out, though. It was a short one. I forgot the details, annoyingly so. It fought a fairly mean Pokemon Hunter instead of Shiny Genesect.
The anime also had Kyurem evolve into its forms without any of its counterparts, so that's not a good point. The anime does what it does, it plays by its own rules and has its own continuity, and thus it's not a good idea to use it to define canon in the games.
