If the development is done entirely or even primarily by Game Freak, then no, it will not be a competent-looking game. They have proved over and over again that they are not capable of delivering a good-looking game in the time allotted to them. However, if Nintendo steps in (which is not that far of a reach after the PR disaster that was Scarlet/Violet), it is possible that they could push the studio to expand or to restructure the development of Pokémon games.
We didn't get any Pokémon games/expansions in 2024, the first time since 2015. If Legends Z-A turns out to be the only one releasing in 2025 (which seems likely since we don't have a release date yet) and they push Gen 10 to 2026, they could be cooking.
