Nintendo hopes to sell 15 million Switch 2 in its first financial year, though some analysts believe actual sales could be closer to 20 million.

Nintendo has updated its website about pre-ordering a Switch 2 console with a warning that because of “very high demand” it can’t promise it will be able to deliver consoles by the June 5 launch date. It even warned that its pre-order emails might not arrive for some until after the console’s launch.
