>>37742957XY sold 16.37m, SM sold 16.14m late in the life of the 3ds and USM sold 8.28m becoming the best selling third version/revision since yellow (that was in the middle of fucking pokémania) on a system that was almost dead.
Also LGPE may be shit but is outpacing every pokémon remake. The series is not dropping sales outside of japan and japan will show up again for gen 8.
