Cost of UHD Blu Ray - Is MS subsidizing Xbone S, or is Sony just milking it?

The reading speed exceeds to 128mb ps, while normal blu rays only go to 58mb p/s. Ultra hd blu rays can be triple layered instead of dual. So unless the PS4 P has a drive that supports these bandwith and supports bdxl which is very unlikely, the PS4 won't support UHD blu ray just as every other blu ray player out there. If you want to play UHD discs you either buy an Xone the Samsung ultra hd blu ray player or the panasonic. Building a UHD drive in your pc is also possible I guess.

You need to differentiate between MB and mbit, the speeds you're referring to are mbit.

 

First: PS4 has a 6x blu-Ray drive, three times faster than the PS3, so it actually exceeds your 128mbit criteria, reaching theoretical peaks of 216mbit/s or 27MB of data throughput per second. 

Also, the standards for BdXL were established a year or two before the Ps4 came out. I would be incredibly surprised if Sony didn't include one of the newer BdXL capable drives in the Og ps4 as I'm sure they assumed that their first party titles would eventually max out the 50gb storage of the 'first gen' blu Ray discs.

Bdxl is more expensive than regular blu ray it is simple as that. I have never seen Sony using a disc bigger than 50gb and they have tried to get as close to the limit as possible. MS doesn't use them either and especially the halo games have huge first day patches for the SP. Even if the PS4 would be able to read those discs which also means the player needs to be able to read 128mbit as you please per second. On each layer and usually the third layer is slower than the first. But Sony mainly didn't include one because of the costs, but a regular blu ray player can't get a firmware update for UHD movies as they did for 3d blu ray.

 

Because the hardware is apparently to different, otherwise companies like LG, Philips and possibly Sony who earn a few royalties with every UHD blu ray sold would have done so already. I very much doubt Sony is plotting against a media format that they partly own although they are not releasing a player anytime soon.
