It is also a question of how many design teams does Shenyang really have. They have the J-11D, J-16, and the J-15 designs. The original J-15 chief designer died. So who is going to be the next head of the naval fighter design team? How many production resources can they dedicate to it, etc. Also, like asif said, they are busy building J-16s. Some claim 80 J-16s will be built until the end of this year. With 60 J-16s already reported to have been spotted thus far. If we assume they will be using the J-16 to replace the JH-7 they might build like 250 J-16s total. That's several years of manufacturing capacity being used just there.
Between the reported new engine developments in China proper and the acquisition of the Su-35 a lot of the Flanker derived programs might have been reevaluated. An ex-chief designer of Chengdu was also promoted to be AVIC executive recently.
So who knows? As far as we know they might even be planning for the CV-16 refit to be longer than we currently expect. This means they might actually share the original airwing between both carriers for all we know about it. We also know there was a stealth fighter program competition and that the FC-31 either lost, or didn't win the competition. So where is the FC-31 competitor design? I even remember claims that China intended to develop a VTOL fighter (which is inane IMHO). There were so many rumours going around that I think it's better to just wait until next year or whatever when CV-17 is operational to see what will happen. Unless there are more leaks in the meantime.
