Wouldn’t surprise me in the slightest.
Either way, that plus Pokemon Gen 8 would make a damn good bundle for Holiday 2019.
I think Switch lite would make more sense next year than a more powerful/bigger Switch. Pokemon is such a portable-centric franchise that I think Nintendo is going to want for Switch to hit it's portable stride even more than it already has. It would definitely boost sales in Japan even beyond how good they already are.
