I'm getting pretty tired of this rhetoric. Yes they do care about visuals. No they don't take shortcuts or neglect to make the graphics look good because "they don't care" or because "the games will sell anyway." We cannot have a conversation about the graphics in Pokemon games without interrogating the incredibly limited amount of time that Gamefreak is given to churn these games out. Legends Arceus was in development for a little over two years. That is a pitiful amount of time to develop a modern HD video game, let alone a giant AAA game.
Zelda BotW was in development for 5 years. SMTV was in development for just as long, if not longer. DQ11 was in development for 4 years. Bravely Default 2 was in development for 3 years! Even that game got more development time than Legends.
Passion is not what is lacking at Gamefreak. In fact, given how good Legends turned out, we can infer that Gamefreak is in fact very passionate about their work. You don't make a game like Legends in a little over two years if your developers are lacking in passion.
The core problem is that The Pokemon Company has failed to adjust to the realities of HD game development. Pokemon games need more time. Throwing more money and bodies at the problem won't fix anything, because good art and robust development tools take time to develop. I do think positive changes are on the way since they have already outsourced a Pokemon game to an outside studio. Perhaps cycling between 2-3 studios is the future of Pokemon, similar to how Activision managed COD.
Either way, the Pokemon Company needs to self reflect and figure out exactly how to move forward. Their current strategy is unsustainable. They need to realize that they simply can't have a Pokemon game every year.
And the gamers who demand a Pokemon game every year also need to realize that they won't ever look good graphically and readjust their expectations of what Pokemon games can accomplish if given such little development time.
