It seems some of Pokémon Unite's soundtrack was datamined within the closed betas. And whereas the soundtrack for the chinese beta was
almost fully synthetised, the one for the canadian beta is
recorded with live instruments!
If you want to hear a preview of this soundtrack or compare music of both betas, here's a
link!
It's always really cool to hear Kageyama's music with high budget, his style really fits live recordings. I really hope he'll bring live instruments for Brilliant Diamond and Shining Pearl. Let's Go was a small step in this direction with the live performances for the piano, guitar and violin, but Pokémon has the means to improve the sound quality of their games.
It would be really nice for TPCi to release soundtracks for spin-off Pokémon games but I think they haven't done that since the Stadium + Snap CD...
A Pokémon Masters soundtrack release would also be really cool, it has some
cool Kageyama music!
