You will rarely, if ever, see many games cross platform--not just because of cost and server issues per say...but of the games console people dirty little secret. If they allowed cross platform, PC people would pown/destroy console people. Once little Johnny got his clock cleaned over and over again by an old fat **bleep** like me on a gaming machine with 10x the power of the PS4 or Xbox One; they would be screaming for mommy and daddy to buy them a gaming PC.
Microsoft tested it and concluded the loss in sales of gaming system (combined with other issues) made cross platform unviable.
computers are better yes but some of use prefer the console feel and will never play pc games like myself.
