So what do you think:
1. Does Marshadow being the only unreleased event Pokemon remaining in Gen VII indicate it might be a quick generation as there would either be no event Pokemon to promote for the 3rd Gen VII Movie? Or do you think GF will go a different direction with the movie or will the 3rd version/sequel/remake introduce a new Pokemon which would become the focus of the 3rd Gen VII Movie?
2. What are your thoughts on more variant Pokemon, especially ones that would be made for previous regions (even though they didn't exist prior in the original games)?
3. Do you think going back to the Kanto region is a good idea? Should it be a remake or sequel? If a sequel, should it happen at the same time as Gen II's story, a bit after, alongside Gen VII's story, or somewhere else in the timeline? Finally should it include Johto? If so, as a post game story or should it be a mixture of going back and forth between the two?
We're teetering on the edge of baseless speculation here, but I think there is enough data to stay on the safe side. At least for point 1) and 2).
I've been wondering about point 1) myself. Magearna was released almost immediately after the games themselves. Ash Hat Pikachu is an event series running until... October, is that right? That means, depending on how you look at it, that 2/3 of the event Pokémon are released within a year of the games. Or 7/8. And they've set a precedent for an unusually quick release schedule too. They appear to be holding off the event outside Japan for some (stupid) reason, meaning it will be a little more spaced out here, but that still doesn't fix the issue; it just means the Japanese will run out of event stuff faster than the rest of us. I
guess they could be throwing out Floette-E in Gen VII too, but it's a stretch.
Another option would be to re-use event legendaries from earlier games. There's a whole crapton of them out there already by now, so nobody would bother if they released some of them again rather than adding new ones. This would also be possible without burying anything suspicious in the code for hackers to find.
There's also the remote possibility that they would break the old convention of not adding new Pokémon mid-generation. They've done it for moves and abilities already, so I guess nothing is impossible. The obvious thing would be to release more Ultra Beasts, since they're apparently the Hot New Thing and their sudden appearance out of nowhere would be completely in line with their lore. But these would have to come after Marshadow in the National Dex, or the Dex order would have to be changed completely, so I'd say it's unlikely that they would go for that solution.
As for point 2), I think more Variant Pokémon is a rather natural way to proceed. It adds new designs, sort of, without bloating the Pokédex. GameFreak already set themselves up for something similar in Mega Evolutions, but dropped that concept like a hot potato as soon as the generation shifted, so it could be that they'd throw regional variants under the bus at first opportunity too. Or they could be thinking that regional variants are a better way to execute the concept of revitalizing old lines, what do I know. Either way, I wouldn't mind them adding regional variants of more old Pokémon. They haven't done a bang of a job for it so far from a competitive standpoint, but they could improve in the future.
And 3)... It's a little wishlist-y, but I guess some general assumptions could be stated anyway. And that is that Kanto is outdated as heck. It's designed with the limitations of the GameBoy in mind. That means a completely rigid grid system, a camera locked to a single angle, extremely limited tilesets, no climate variation, and rather monotonous dungeons. To bring Kanto up to par would necessitate a lot of re-imagining. Town layouts are completely wonky and would have to be redone. The buildings are identical all over the region, the routes are often too cramped, and the detail level of things in general is waaaaay lower than what we've grown used to since Gen IV or so. The designers would basically have two choices: Accept an outdated-looking Kanto, or add details that weren't there before. This would radically change the atmosphere of certain places (for instance Cinnabar Island, which in its latest iteration is a handful of buildings on a concrete slab in the ocean). It wouldn't be the Kanto we're used to. There would be controversy.
Personally, I'd let the designers loose completely, and build a Kanto experience from scratch. Keep the basic layout, redesign everything else. Let nothing be sacred, the time of Gen I Kanto has passed (twice) and is preserved for posterity in the Gen I (and to some extent III) games, so no need to recreate it faithfully once again. I haven't worked out the details of everything, but elaborating here would be against the wishlisting rule anyway.
