Just putting more gas on the fire, at least the planform suggest this is closest to the VG carrier fighter, but... some time ago there was a rumour about big changes which some may and some may not like on the 6th gens or maybe just J-36. What if this is what we're looking at? What if the J-36 is the demonstrator but this is the real deal? Of course this raises more questions as to the whole timing of the Chengdu/Shenyang demonstrators/prototypes, f.e. did the J-36 flew well before 2024, is it actually what we saw in the sat pics back in 2021? Again, this is just speculation.
Overall, for now the two most likely possibilities seem either the 6th gen VG carrier fighter prototype/demonstrator or a high end CCA.
