Latest Wild Area Max Raids

Other than Snorlax, Delibird, Magikarp, and Milcery (which all ran parallel to other events), these Max Raid events seem to follow a steady pattern of a single, dual-version spotlight Gigantamax Pokémon and then two pairs of version-exclusive Gigantamax Pokémon:

Butterfree, Drednaw/Corviknight, Sandaconda/Centiskorch

Alcremie (with its various flavors being version-exclusive), Coalossal/Lapras, Flapple/Appletun

Toxtricity (again, with the forms being version-exclusive), Kingler/Orbeetle, Grimmsnarl/Hatterene

I'm going to go ahead and hazard a guess that the next one will have Duraludon as the spotlight Pokémon, with the exclusives for Sword being Machamp and Copperajah (Rose's ace), and the exclusives for Shield being Gengar and Garbodor (Oleana's ace). Alternatively, I guess Garbodor could be the spotlight since it's the only Unovan Pokémon with a G-Max form, with Duraludon/Copperajah being version-exclusive Steel-types, but Copperajah/Garbodor makes more sense to me based on the story.

Assuming that's right, then that would leave Charizard and Melmetal as the only Gigantamax forms left to get increased distributions, though I could imagine neither of them getting that same kind of treatment since Charizard is already given to you as an in-game gift and since Melmetal is a Mythical (so they might want to distribute it some other way).
