I think PLAAF would be based mainly on J-20 and J-16 in the near future.
Both have excellent range, but J-20 lacks ability to carry large anti-ground ordnance without compromising stealth, so she will be mainly air focused.
J-16 is based on mature platform with large space, power and weight carrying capacity for continuous improvements/upgrades. She can be used as bomb truck but with stand-off anti-ground munitions as modern battlefield may be too risky for A-10 type operations or even F-16 types. She carries enough fuel to loiter on standby, swooping in no closer than absolutely necessary to fire her munitions then fly out of enemy weapons range again.
Having two people on the plane helps with sharing workload, and she is also more than capable of defending herself against air threats if needed without needing extra escorts, being based off air-superiority platform. So we'll start to see J-16 replacing the roles of many other planes like Q-5 and JH-7s. They may even start replacing older J-11s as the end of their useful airframe time draws near.
