Just as poor as it's PS4 performance. Perhaps SE should bite the bullet and go mobile next time.
While I don't agree that this Switch debut is some huge bomb I don't think PS4 comparison really works either. Playstation owners bought the game already back on PS3 and Vita. Because of that it was always going to sell little on PS4 only 1.5 years later with no big changes. This is first time Nintendo owners have chance play the game so theoretically there should be bigger base to buy it and I think it certainly could have sold more than this.
