If Nintendo,MS,Sony agreed on One Console standard for nextgen, and shared exclusives. Who would come out on top?.

[Platina]

I don't really get how this would work

If they all make the same console that can play all games, why would they bother making the console in the first place? All are the same and will compete so it's basically a loss for everyone?

I guess PS4 would win though, to answer the question
