Considering Switch hasn't had it's second holiday yet, I'd say it's holding pretty well. Honestly not that far behind PS4. I think it will have a killer holiday, hopefully with bundles and great BF sales to go alongside Pokemon and Smash. I do think they could have had a much better first half of 2018 with just one big release, but oh well. I think sales are going to pick up soon.
