There were over 50 opponents in the PWT. Due to the shift from 2D to 3D, every single one of them would have needed a new 3D model. The sprites used in BW2 basically already existed, since every region except Hoenn had been represented in the DS generation, so they were mostly pulling assets from old games. Making all these new models for X/Y would have basically doubled their workload for trainer models.
