A very large chunk of Nintendo's profits were made in the console business. I don't think they'll stop anytime soon. (Unless Switch super terrible).
Either way, I don't want them to go 3rd party. I want them to make much need restructuring efforts in their company and be successful again in the hardware business.
I always had the feeling that their software would decline if they moved to 3rd party development. I know a lot of people who share this sentiment as well.
