If we're talking about GameFreak in the Switch-era, then no problem with the statement. However, they were some of the rarest devs to actually push their hardwares to the limit. 

The 3DS games were incredibly demanding, while the DS used 3D assests as well and continued to evolve the 2D pixel sprites to almost perfection at the end of the 5th Gen.

I'd actually say the Switch is the first console where GF hasn't been able to efficiently push the hardware to it's limit as they could.

I actually disagree with this. I'd rather they have less Pokemon in future games rather than more.

It really annoys me how many Pokemon from previous gens they put in the new ones. The different regions in Pokemon don't feel that different if they all share the same Pokemon. I really loved gen 5 and Isshu for that reason. It only had new Pokemon, none of the old ones at all, which really made it feel new, unique and interesting. Unfortunately that doesn't seem like something that'll ever happen again, especially not with the recent gen 1 nostalgia drive Gamefreak have been on. But I'd still love more Pokemon that can only be found in a specific region, nowhere else, that makes those Pokemon, the region they're in and the game more interesting IMO.

Why would you want the same content you've already got rather than more new content? Especially when a lot of that content you've already got isn't that good. IMO the vast majority of gen 1 Pokemon designs are crap, so all of the gen 1 pandering Gamefreak has done lately has been pretty annoying to say the least.

Plus variety is nice. I can't think of any other game that re-uses the exact same enemies in every single entry and I certainly don't want any games like that, it'd be boring.

Pretty sure I already explained that, but it's not just "content". I like the Pokemon world more than I like the Pokemon games, I want it to be an interesting, varied world and I don't want that to be ruined just for the sake of quantity.

To compare it to our world, are Pigeons interesting? No, because they're everywhere. Pigeons are boring. Are Pandas interesting? Yeah, people love Pandas, they're exciting because they're only found in 1 place. That's what I want with Pokemon too. It's especially relevant when you take into account the geography of the Pokemon world. Kanto and Johto are literally right next to each other, you can walk from one to the other, so those two having a lot of overlap in terms of Pokemon species makes a lot of sense. However places that are distant from each other and are made to look exotic because of that should have minimal if any overlap. Going to new exciting exotic locations is interesting to me, that's what I want to do in the games. Going to those locations and just finding Pidgeys, Ponytas & Oddish all over the place takes away all of that excitement.

By far the most exiting thing announced during Friday's Pokemon presentation was Pokemon Legends Arceus.

This is a massive, open world Pokemon game where you venture out into the wild and explore and find Pokemon living in the world.  It looks like Pokemon meets Breath of the Wild, and the trailer was trying to give Breath of the Wild vibes with certain shots.  This seems to be the game many of us wanted Sword and Shield to be, from the graphics being a huge improvement to the freedom and openness of the game.

That said, there are some problems.  The world seems pretty barren, with very few Pokemon on screen at any one time and no large Pokemon shown off to give off a sense of awe.  In addition, the framerate is bad, with some Pokemon looking like they are moving in single digit framerates.  Hopefully this is because they showed off an early unoptimized build since the game is at least a year away, but given Gamefreak's history of being unable to push whatever hardware they were working on there's plenty of reason for concern with the graphics.
