It's on track to have the best 1st year ever for a console, with something around 15m. On top of that, rumor has it that it may ship between 25m-30m next year, so that would put it at 40m~45m on its first 2 years. Besides that, I suspect this system will be supported for 6 years as their main system, like the 3DS, so I'd say it's very possible that Switch will finish on top.
Bet with Teeqoz for 2 weeks of avatar and sig control that Super Mario Odyssey would ship more than 7m on its first 2 months. The game shipped 9.07m, so I won
