I actually feel bad for the people over at GameFreak getting so much crap about how bad their games are, and then they get compared to other better looking games. Funny enough, the amount of staff in GameFreak is a staggering 150-190 people, while the staff who have been working on better looking games were made by 300+ people and have been in the programming phase for much longer.
For Sword and Shield, they couldn't put the same models from USUM to SwSh because the models just didn't translate well, causing them to make them all from scratch to make it better for the Switch's engine. Plus, they have to make more models for the Dynamaxed Pokemon, and they have to make those from scratch as they can't just stretch the models. That's like going on PhotoShop, getting a small image, and stretching it out and expecting it to look like the original, but better.
Sadly, their tweets seem like they are grasping at straws to explain their lack of being able to make all the Pokemon come back for the new games due to all the death threats and hate, causing their reasons to fall flat. This is just a game and despite the fact that fans are invested in this franchise, the company isn't obliged to follow what their fans want and they'll do what they want with what they have available. I get that people are mad, but complaining about the inevitability of the status of the game is not going to get anyone anywhere and there will be plenty of people buying the games anyway, making all those threats and hateful comments a moot point besides making the fanbase seem rotten to the core.
Also, about the graphics, yes the graphics could look better but the games don't have to look good to be a selling point (although, sadly that is usually the main point there when it comes to marketing). The fact that it is Pokemon is enough for some to buy it. Also, it is highly likely that they are unable to refine the graphics when showing trailers and teasers. Maybe they'll make the game look 10x better when they release it, they are just not wanting to show what the final product will look like yet. Their graphics being compared to Breath of the Wild's graphics is kind of unfair as BotW was built by way more people with way more time than the developers and staff over at GameFreak.
