4K Blu Ray is not about the price of the disc drive.
Hardware of a UHD disc drive is the same as a standard Blu Ray drive. You only might need a firmware update.
Now, you do need the decoderstuff, HDCP 2.2 and so on. Basically all the stuff that's needed for 4K streams.
Sony doesn't want you to buy 4K discs. They want to have total control on movie content and push streaming further.
