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.

But they aren't plotting against the blu Ray association, obviously. It would be more logical to assume that they wouldn't patch in UHD because it would bare the question, "then why the hell are we being charged a premium for UHD players when newer legacy drives are just patchable"? That's not a plot, that's a conflict of interest and one that would piss off the rest of the major tech giants involved in the creation of Blu Ray.

 

Anyway, there is extremely strong and compelling evidence that the PS4 can be UHD compatible. In fact the more I've looked into it the past few days the more I've come to see that this is not a hardware barrier for Sony, and that everyone's about to feel really dumb for jumping on this UHD bandwagon. I highly suggest you read these and hope that you stop asserting your opinions as fact, because you have done nothing to prove your argument. These links are from summer 2015. Please. Take a look.

4K UHD is an ace in Sonys sleeve. They're waiting to play it. 

 

 

edit: also, the hardware is actually barely different at all d: same laser diode, main difference being codecs and read speed, the latter of which we now know the ps4 is fast enough to read 4K video. It boils down to a software solution needed for codecs (emulating h.265) applied via firmware.
