BLACK FRIDAY: who will win of the big 3?

[JRPGfan]

Everyone that thinks the Switch will sell the most on "BLACK FRIDAY" can you answear why?

Is there going to be a price cut/special offer? something to make it sell more that day/those days?

Because PS4/XB1 are going down to the 190$ ish range.
Which should make them sell much more then.
