To be honest, the only way we will get great sounding tracks like in the 16 bit and 32 bit era is if the composers draw back on the number of channels they have.
Unlike graphics, music seems to get worse the more technology advances. Somehow they dont seem to get that too many sounds just get filtered as noise to our brains instead of melodies.
Most JRPG's have crappy soundtracks where they used to great in the past. The only exception is Nier.
