The console war as we've known it for so long is dead.
If you're someone that really cares about this, then you need to just know that in terms of flat out number of consoles sold, the PlayStation 5 will 'win' that particular battle. That isn't what matters so much any more, however. Microsoft will be very content in shifting less consoles as long as they sell more subscriptions. It's the way the market is going and I think Microsoft will eventually be the market leader once they have more good exclusives.
Probably an unpopular opinion, but despite them being no.1 in gaming in most people's eyes at the moment (including mine), I think Sony would be the first to go out of business between themselves, Microsoft, and Nintendo if it ever came to it. It sounds odd, but I think it'd be the most likely thing to happen even though I think any of them going out of business in a gaming sense is out of the question for an incredibly long time.
I think Nintendo and Sony still do well because so many people are still accustomed to owning a cartridge or disc, or at least a digital copy of a game. I'm 30-years-old now and this will always be my preferred way to purchase media in terms of video games, but I have very much adapted to streaming any other form of media. Maybe I will just accept it one day for games too? I am convinced that the next generation of gamers will be ones who care much less about collecting physical games and that will be the niche market, much like vinyl for example. At the moment, I'd say most gamers in their late teens, and all of us in our 20's, 30's, 40's that still game are mostly set in our ways and want it to stay that way. But, it won't be the case for that much longer when we're outnumbered by more and more who just want to get the game quick, download, stream it etc. This is when I believe Sony and NIntendo will unfortunately struggle more as I can't see them always being able to one-up Microsoft and soon to be Google purely because of their exclusives, as the latter will have far better services and I'd almost guarantee they could afford to charge less.
Sad times ahead.
