Based on the supply constraints, I'd say the Switch will fully eclipse the Wii U just after its 1 year anniversary in late March / early April, so right on the 2018 Q1/Q2 borderline.
Had hardware supply not been an issue, there was a real possibility Switch could've done it before the end of the year.
Edit: I'll say the final week of March 2018 is when the Switch will officially pass the Wii U in LTD sales, so end of Q1 '18.

You know I was always wondering why no one ever used the dollar sign for $ony, but then I realized they have no money so it would be pointless.
