It's not only the top 20. We don't track multiplats because they're not of any great importance and, given the amount of multiplats that can be in the charts at once, it can become a nightmare to update. We only track console exclusive preorders, and only in the week of release UNLESS they manage to get into the top 20 outside of the month of release. 

P0isonparadise is doing a remarkably good job so I do hope that exclamation mark is meant to express playfulness (I'm assuming it is).

Nooooooo switch losing its momentum when it seemed strongest

I really thought that Nintendo had the stock issues in control, by now, in NA. Probably, Amazon was being stingy with their Nintendo orders again.

As far as I can tell, stock issues seem much worse on Amazon than anywhere else.   I think Amazon's lax approach to dealing wuth scalpers who gobble up tons of stock via bots .5 seconds after the new stock comes in has made them somewhat last in line for shipments.  And not just from Nintendo, some PS4 bundles had momentary stock issues earlier this year that were totally anomalous relative to the rest of the market.  Not nearly as bad as the Switch of course.

New stock is coming to Amazon in the coming week according to the site.

You could say the same thing with the PS4
