As much as I want to be able to give Pokemon Sword and Shield more credit, the graphics really do need a lot of work. I hope they spend the next few months polishing the games and ironing out the issues that were present in the E3 build. It looked rough in that build even if some elements occasionally worked out well. I'm still not willing to give a ton of credit to the game for being a "substantial improvement over the 3DS games" because it has to be that regardless of anything else. I look at the graphical quality of other main AAA Nintendo games on Switch, and it stands out pretty sharply to the others in a bad way. Graphics aren't everything to games of course, but there has been a certain standard established by so much of the first party Nintendo output that feels noticeably missing. The good news is that is something Game Freak can and should be doing in the next few months.
But then again, I'm also concerned quite a bit about stuff well outside of Dexit related issues. The more I read about Masuda's comments in the past regarding Pokemon, the more I get the sense that his vision for Pokemon conflicts with the type of Pokemon game I'm interested in. I want stuff like a competent and enjoyable post game (doesn't have to be great, but I want there to be something I can do post beating the Champion that lasts longer than a single questline), less hand holding or at the very least skip-able hand holding, and more mechanics outside of battle.
Those are all things we'll need to watch Pokemon Sword and Shield to see if they achieve, and the good news is they're far from set in stone, but I'm also not hopeful with the precedent set by something like XY that was a similar leap in game design, but really struggled with the elements I'm interested in. Dexit is honestly one of my smallest issues with the game on its own. If it has these other things, I'm fine with it, but Game Freak does not have a great track record and when they talk about not focusing on Pokemon anymore, it also doesn't exactly inspire confidence.
