Once more; I know what shipped means, the point is that this was never specified.
In some cases, the difference can be vast, the Wii U was selling on its initial shipment one whole year after release. I know, I know, this isn't the Wii U, but it suggest that shipped numbers don't tell us what we need to know short term. How many units that end up in customer hands, and at which pace, tells us of the market's movement, retail orders do not in nearly the same capacity.
Wii U did had more shipments after launch each quarter in any case even if those shipment numbers were terrible. Shipment show us how some console is selling in any case, if Wii U case it was selling terrible and thats why had terible shipments, in Switch case Switch is selling great and thats why we have strong shipments, at end in any case shipments equals sold numbers, especially in this case where PAP is dead and not active platform in any case.
