I think this is the largest delay in the history of the universe, SORRY for that. I've been a little inactive for the past... year, really.
So, now the remakes are out (for a long time) and the Frontier Brains didn't even get in. Shame, I'd really like to see how they'd look after a redesign. But I think all the references are curious; the Battle Tower model, the mentions about Scott and the Pike Queen... I wonder if they'll pull HGSS on us and include the Hoenn Frontier in the next Kalos game(s). Sure, it would be in another region, but we know there are equal Frontiers in the Pokémon World, canonically — I remember Caitlin mentioning there are Battle Castles in Sinnoh and Johto so, if anything, the only non-canon part about these is both regions having the same Frontier Brains.
And turns out there is a problem with Mega Evolution, since X and Y state the first Pokémon to Mega Evolve was a Lucario, and ORAS state the first Mega Evolution witnessed by mankind was Rayquaza's. Perhaps the former is referring specifically to a Mega Stone-triggered Mega Evolution, while the latter refers to Mega Evolution in general? Now I wonder whether the next Kalos game(s) will keep that in mind or simply ignore.
And now a multiverse was referenced. Interesting. That potentially makes all versions canon; for instance, there is a universe where Black and Black 2 are the canon story (I still think they make more sense, personally), another where White and White 2 are. One for HeartGold, one for SoulSilver. And so on.
Again, sorry for the gigantic delay.
