WZ-8 revealed in 2019 as a total triangular craft, differs from previous speculation of this shape.
But satellite footage from well before 2019 reveal of WZ-8 already showed the actual drone. Back then we were speculating on what the traingular craft was.
I remember there was two separate and different satellite photos where Chinese intentionally placed the triangular WZ-8 outside on the tarmac for intelligence observers before its more close reveal in 2019 which basically confirmed that the satellite "exposed" drone was WZ-8 we saw in 2019 parade.
Then the government later basically announced that the WZ-8 has been used many times (before the parade) and have flown missions around SCS and Taiwan seemingly without being detected (believable since it is a very small RCS aircraft flying near space at high supersonic speeds.
For some reason I seem to recall at least one satellite photo showing a craft with the shape of the first image (CGI one) where the fuselage/leading edge has a different sweep angle compared to the wing. Maybe I'm misremembering but I do recall there were two mystery black drones - one triangular later shown as WZ-8 and the other has the plan view of the first craft. They could be built around the same fuselage design structure and the first craft might be used for some other purpose and for slower speeds - greater agility than WZ-8.
The bulkheads shown in your image has also been seen in the past - many years ago. Basically the same structure and it seems to fit a craft with those variable sweep angles (whatever the correct aerodynamic terminology is). Unlikely for hypersonic drone due to the sweep angle (of the CGI stuff) but could be for this aircraft or the Dark Sword UCAV.
