That's a fair point. I thought you were shitting on the possibility of it being bad because it was 2D. Yaknow, some call the Switch a "pet" platform because it's the weak one in the market, hence "lol2Dgamez" trolls. My bad.
To your point, a good question is to ask who would even compose for the game? Michiru Yamane left after Order of Ecclesia, and she was the goddess that was involved in most of the games since Bloodlines.
If I were to guess Konami would just probably get an internal team to do re-arrangements on the cheap rather than make totally new music.
