I like the Xbox because they changed so much in the console ecosystem, play anywhere, backwards compatibility without extra cost.
Sony makes zero dollars off of the consoles, and while they do enjoy taking their PS Store royalties rather than giving it up to Steam, they also have a huge collection of first party studios that might even be a more important business.
And it’s not like Sony is giving their big console releases PC ports on day one, if you want to own them right away you have to buy a PlayStation.
Every Steam Machine sold that plays Sony's exclusives is a genuine threat to Sony's control over the gaming market. The more I think about it, the more I believe Sony's games coming to PC is over since yesterday's announcement.
