Do you think they will still develop a VTOL variant and if so whether they will adapt it from J-20 or J-35?
I think maybe the 35 as it is already navalised.
I doubt it.
This has also been extensively discussed in the past.
It's possible they will develop some tech demonstrators for a STOVL capable fighter-esque airframe for the purposes of industry use, but at this stage I would be surprised if the PLA was interested in one given where they are with everything else.
