I really doubt they're gonna help their main competitor when it's struggling.
1.) The XB1 is selling better than the 360 did, why do you say things like struggling? If you have 2 billion and I have 1 billion I'm still a billionaire bruh
2.) How does cross play help one system and hurt another

This would be another reason for sony only gamers to NOT buy an xbox, no need to
But if you look at things from a purely fanboy perspective? You'll never see reality brehs
3.) Greener side benefits from a much better matchmaking system than what sony offers, thus making the overall community better than the community on sony. Whenever people would come to xbox to play games they love on sony? They get crushed and usually run back to sony so they can play an inferior product. Usually the blame will be put on the superior xbox controller but we all know that's a copout
