If anyone, it would be Sony.
I can see the Playstation brand breaking away from Sony (To be Interdependent? or perhaps Purchased by a Google or Apple?)
In some ways we will still have all 3 (MS, Nintendo and PlayStation), but its possible PlayStation will no longer be a "Sony" Brand.
I also think the market is going to be changing significantly after next gen, and its very possible there will be no "Console" by Sony, instead going 100% to Cloud Gaming (might be a very smart purchase they just made).
