I actually agree with Phil: Sony's Reasoning For Blocking Cross-Play Is "Unhealthy,"

Can speculate all you like, the only current fact is that MS and NN are allowing it and not sony. 

Actually it happened this generation with Final Fantasy XIV. Sony allwoed cross play, and MS refused.

Sony's stance here is weird. They allow it for some games, and not for others. But that comment about keeping younger players safe in Minecraft was obvious BS.

Maybe Sony's doesnt' want Microsoft to pad their Xbox Live membership and logged hours with PlayStation users.
