To give some perspective:
=> there was 1 Switch model on amazon in september in the top 30, placed at #15.
=> there are 3 Switch models in october, placed at #7, #12 and #21. And that is 8 days before Mario Odyssey...
==> Switch in october will most likely have phenomenal sales.
Switch won in Sept and obviously guaranteed for Oct.
Possible switch wins Nov+dec?
