Well, per service timeline it's quite likely the coming flanker replacement in the first place; certainly fighter flankers, for whom career is in the autumn phase.
J-20 is massively early to touch, j-10 may or may not get direct replacement at all, depending on how comfortable China is about its surroundings.
J-36 is "something else" category (though it isn't inconceivable that some bomber units may be transferred over onto it).
