Ah, I see. Either way we slice it we can say that the Switch outsold the XB1 in three short years. I think gapchartz, done by this site, will show that neither XB1, nor XB2 will be able to keep up with aligned Switch sales.
But I wasn't really arguing X1 vs Switch sales. I was just stating that, at the end of the day, people will see the X1 as the 2nd place of the 8th generation.
As for the X2, I really don't like making predictions without any data to rely on.
