I'm not sure and I also don'the really care since I can already crush both X1 and PS4 players.
What they should do is fuck both Sony and MS and put up their own session tracking servers and allow anyone to play with anyone even in a party. There is really no need to connect the networks directly to each other.

That would be a really good idea
