BDXL will not be a big change to 4K, BDXL max space is 100-128GB. Has the codecs are currently 128GB is not even close for the space needed for 4K. BDXL will be for higher quaility 1080p, ability to spread long 1080p movies over 1 disc, fit extras on to fewer disc's etc.

A quote from Vinpower Digital CEO:

“Blu-ray as a format has already opened the doors to greater storage capability for all aspects of digital storage, yet innovations in fields such as 3-D video content and archival storage have created a need for even higher capacity," explains Vinpower Digital C.E.O., Calvin Chang. "So, the introduction of the BDXL media opens the door to greater creativity and development across all content creation, especially in the field of filmmaking. That’s why it was critical that Vinpower offer duplication equipment with the Pioneer BDR-206MBK drive, which is capable of reliably copying this new higher capacity media format.”
