This is only my speculation, but i believe there will be no dedicated CAS planes anymore. The j10 and j16, being multirole, will do the support missions. And perhaps some of the personnel (or even some bases) housing Q5 previously may get some UAVs. Which again won't be purely for CAS but may to a small degree also be trained for that role.
Exactly ... for most of the former CAs roles, helicopters like the new Z-10K and UAVs and probably as pointed out the JL-10 are used.
