Correct, people have been waiting for the Pokemon games to do something, anything different or interesting for decades. They finally got about halfway there with Legends Arceus' concept and then for some reason decided to take a huge step backward with Legends Z-A. Mainline games are even worse, to the extent that they might as well still be getting ported to the original Game Boy. For that matter, you could make them wholly text-based and the experience would be fundamentally the same (not to mention have far fewer bugs/performance issues).
Beast of Reincarnation seems like GameFreak's final chance to prove that they're bored to tears with the Pokemon franchise and not just an F tier developer in general. Either way they should hand the reins off to a more passionate/competent studio, and it seems Nintendo have chosen Koei Tecmo to fill that role (they're credited in the Winds and Waves trailer). The critical and commercial success of Pokopia has likely accelerated that transition as well.
