Don't know, but I hope to see a new dedicated DMR to come with this. I swear to god if it's just another rebrand of the QBU 191 and not the sino scar...

A more refined QBU-191 would be pretty fine tbh. For a mass fielded DMR, QBU-191 has most of the important characteristics one needs.

A collector got one, but it was a steel case, not a brass one. It is just an experimental round, probably just to test the potential of the 6.8mm.

Given commercial availability of .277 fury I am not surprised they could reverse engineer a surrogate cartridge for testing.
however given the amount of heaven and earth the PLA has been moving to adopt QJY 201 in 7.62x51mm and their own 8.6x70mm I doubt they are adopting anything different anytime soon. Army’s are big organizations and they don’t turn on a Yuan and give change.
Besides both 6.8x51mm and the 5.8x42mm are takes of a common cartridge concept. Using the same ammunition between Carbine/Rifle (QBZ192,QBZ191/M7 Raptor,M7) DMR (QBU191/M7) LMG (QJS161/M250). Adopting 6.8x50mm would require a majority overhaul of the process well breaking the commonality among the sections.

Here's the full academic paper on the experimental 6.8mm round. It was likely created to investigate its lethality against protective plates –– among other performance aspects –– to see if the current crop of protective equipment is sufficient in future scenarios against adversaries equipped with 6.8mm round.

So their conclusion is 6.8mm with AP core can penetrate NJI level IV plate

167.9 grain 93W tungsten core should be 10%+ heavier than the XM-1184, but the velocity is only 740m/s at a simulated distance of 100m. I don't know the velocity of the XM-1184 at this distance, but it should be a bit higher. It can basically be regarded as the XM-1184

PLA's standard issued system ballistic plates definitely won't hold up, but reinforced plates (GJB3+ level) should withstand 1-2 rounds at 100m, and more stable at the 400m engagement distance preset by the PLA and planned by NGSW itself. For the next generation of ballistic plates, they can just use better materials like boron carbide or just make it thicker, shouldn't be a big problem.
