Oh you think they will "really" underestimate it ?....
Apologize, I am one of those who believe that they can accurately estimate and plan an artificial shortage...Just a little bit, enough to make a strong marketing punch.
Eh, they definitely underestimated the original Switch launch, that thing was impossible to find throughout the entirety of 2017 pretty much.
On-topic, though, I think it's possible, yeah. Switch Lite and Pokémon will be (unfortunately) insane.
