Yes, yes, no.
I have no idea at all about DK showing up and being released this year. Just guessing.
On Switch sales.....A 2D Donkey Kong game won't make any difference. I expect Switch sales will be about the same as last year if XB and PS remain supply constrained and Switch is widely available. Switch sales may fall slightly if XB and PS5 are widely available. Obviously, Switch can only sell units that exist, so supply constraints could come into play there as well.
