Can the Switch realistically surpass XBOX One's sales figures?

I'm trying to work out if you're asking if it will outsell it before the next Xbox comes out, or if you're asking if it will outsell the Xbox lifetime.

Because lifetime is an obvious win for the Switch. Xbo will sell under 60m lifetime. Switch will do more then that.

Will have outsold xbo before the end of 2020.

I guess my question is whether it will outsell it, but it is important to factor in whether this will be before or after Microsoft has released a successor.
