Yeah, you're right on all those fronts.. but they do own some large IP like Call of Duty which will continue to generate money for them for the foreseeable future.
I did hear the speculation about Xbox as well and I hope it's not true. I quite like the Xbox as a console (Series X was the first one I bought, used to be on PlayStation before that). Competition is good for the console space, and Nintendo and PlayStation aren't really competitors IMO. The audience for Switch and PS/Xbox isn't the same.
Yeah I’d be bummed too. I think they were on to something with the Series S (my Xbox currently) in particular but they blew whatever interest they had at the start. For $300 it’s been a fantastic investment, even though it’s collecting dust now.
