I don't think they will be able to as the areal density is higher. Current Blurays are 25GB per layer, and the UHDBD is reported to be 33GB per layer.

UHD blu ray uses the same wavelength of violet laser as current blu-ray drives, and the quadruple layer disc format was already in use for data archiving (BD-XL). The main difference is that the new players have HDCP 2.2, HDMI 2.0, and more power to decode the HEVC compression.
So at the very least your manufacturer needs to give you a firmware upgrade for the new HDCP and to recognize the new media.
