It would have seemed sort of reasonable in 2013 where the Wii U was clearly struggling and the 3DS was barely gaining decent traction but still lagged against the DS. In late 2020 it just seems sort of insane when the Switch had already beat the lifetime sales the Xbox One in 3 years and brushing up against 360 numbers, Animal Crossing had a launch bigger than Halo 3 IIRC and Mario Kart 8 was still trucking along regularly in the sales chart despite already being over a half decade on.
