We saw this with the PS4 once the Switch launched as well. The year the Switch launched (2017) was actually PS4's best selling year. I believe it was also Xbox One's second best selling year that year. Just because a new product is on the market doesn't mean that sales for the original product will be cannibalized, unless that product is a direct successor (e.g. PS3 sales are cannibalized by the launch of PS4, relatively speaking).
