So Xbox players will be beta testing and PS4 players will get the finished product.
I am OK with this. This game will be a buggy mess at first if the PC launch is anything to go by. PC version is running really good these days, which proves the quality of the devs at hand.
Look, if MS wants to pay $$$ to keep an alpha and beta off of PS4, I think that is OK. Shady, yes. It's nothing Sony hasn't done in the past, though and Sony has no room to throw shade because of how they pay for Destiny DLC. PS4 players will very obviously get the game. This is just how these behemoth companies do business. It's not good for consumers, but sadly we have to live with it.
