If SAC doesn't get the J-31 contract, it could be in the same boat as Boeing, without any manned combat programs once the Flanker variants wrap up.
Yeah, that's a real possibility. J-31 is their only next-gen manned fighter program in the foreseeable future, which is increasingly less likely to be selected by either PLAAF or PLANAF. Export is a big if.
They will likely be involved as subcontractor to other companies though (CAC, XAC) in future programs, as they are rumored being in the J-20 program.
