It probably means nothing and you're looking too much into it.
Not really, Rayquaza wasn't available in X and Y even though it has been confirmed to be the first-ever Pokemon to Mega Evolve.
That wasn't established yet, and Rayquaza doesn't even have a Mega Stone. Eternatus is the creator of Dynamax, and every game that features Dyamaxing has to either include it or reference that it attacked the region during the first Darkest Day in order to avoid violating Sword and Shield's lore.
ORAS already contradicted X and Y's lore, it isn't out of the realm of possibility of the D/P remakes having some sort of contradiction against Sw/Sh's lore.
Except it was firmly established that Dynamax did not exist until the meteor containing Eternatus struck Galar. And, Sinnoh might not even have Dynamax if it's a Gen 9 game, which I think that they will be.
D/P remakes can easily be Gen 8 games to further feature Dynamaxing. Also, it was firmly established in X and Y that Mega Evolution originated in Kalos even though ORAS contradicted that statement.
That would leave Gen 9 with nothing aside from the main games and possible DLC, if we get Let's Go Johto this gen too.
Gen 9 could get the Gen 5 remakes, simple as that.
Too early for that.
Eh, not really.
Yes, BW are too new to be remade. And, I can't see them doing Let's Go Hoenn in Gen 9 either.
It's never too early to remake a game that has passed its 10th anniversary.
BW is too much like the modern games, except for the absence of the Exp. All, the Fairy type, and 3D graphics. I think that they won't be remade until the Switch's successor is released.
It has nothing to do with keeping up with patterns, modern or not. The Switch can easily get a Gen 5 remake regardless of past "patterns"
