I like the direction MS is taking with their ecosystem.
- pushing Game Pass significantly
- will probably the be the leading contender for streaming based on their vast enterprise ecosystem and cloud infrastructure.
- don't really give a shit if you play on the PC, Xbox, any device that can stream.
- making significant contributions to their software with 7 new developing studios.
As for Nintendo, they got their niche and it will continue to be good for years to come unless people get sick of Mario, Zelda and Pokemon.
And for Sony, they got first party for now but lets see what happens with Xbox over the next few years. Also, I will be very interested in seeing if old dick Sony comes back and tries to be cocky as shit again. I don't think Sony can do another PS4 and be as successful.
