I think they will continue to add more 4th gen fighters, if only to replace those 3rd gen fighters. But they won't show a torrid pace for it. Just maybe a regiment or two for about a year or a year and a half for each type, mainly J-11B, J-10, JH-7A and even J-8F. I would expect they would build a second regiment of J-11B, and sooner or later the PLANAF will get their updates. The defense industry is also a job creation industry, and thus they will continue to build these planes.
If you consider your fighters not as advanced, you may like to compensate with numbers. If there is any feeling of perceived technological inferiority in the PLAAF, they will try to compensate with numbers. Not with numbers of really cheap, less capable aircraft, but at least with numbers of more capable aircraft even if they perceive the opponent still has technological superiority. Both numbers and technology are a two flank attack to reduce the capability gap. The fact alone they still produce and deploy the J-8F tells you a bit of their mindset.
The question with the J-11s is what to do with all the older planes? Do you want to upgrade them, at least to the same radar and electronics standard as the J-11B?
