I had heard about it too a few months ago. Games that use wifi features just become unplayable (like Splatoon) unless you have the premium. Pokken would still work, though just can't play online without it. Yeah it sucks, but what can you do. Hopefully it means a more dedicated server to everything on.

I heard it's been delayed, but we will soon see I suppose. I'll have to add those of you with a Switch soon too. Don't play mine very much right now honestly though.
