Will the Nintendo Switch make it to 20 million?

[VAMatt]

The main problem of predicting lifetime sales of a console, especially now that we have mid generation updates, is that we have no idea how long that lifetime will be. If Sony calls every console they make from here on out a PlayStation 4, then 150 million is nothing. But, if PlayStation 5 comes three years from now, 150 million is totally out of the question.
