The Switch will sell a bit more than 10 million units this fiscal year. So even a 50 % decline of Switch sales next fiscal year will still see 5 million Switch units being sold next fiscal year. Which will take Switch roughly 5 million units from PS2.
Its 100 % sure that Switch will pass DS total sales, and maybe 70 % that they will pass PS2 total sales as well. It will depend on if Nintendo will continue to produce Switch units after the release of Switch 2 which i think they will do.
