Answer: (what i've heard) No...i've been reading they wont support streaming over from pc to console anymore without introducing some paywall app inbetween. This is the reason why my x1 will be used for games whilst the ps4 will be used for media entertainment.
My guess, they are going to see how many people pay for the different media services they offer. If it's an abysmal number I am sure they will implement something. If they are making money off of them, I wouldn't hold your breath.
Bottom line, MS will only change if something backfires on them, ex...all their initial announcement policies.
