Nah. I am just a lurker. I do not have any inside contacts. These are just reasonable guesses based on available leaks.
Basically what people who are in the know say and what they do not say.
For example Sun Cong has given multiple interviews so we got an idea of what the FC-31 was initially funded for. It is basically like what you said.
However then you can add to that comments from people who supposedly have inside knowledge of Chengdu. A year ago they would just say that the contract was not made yet. That CAC was still in the running. Now they just simply shut up and make evasive comments. What that tells me is that it is quite likely that the naval contractor has been decided already. I think it is Shenyang. However it is likely not Sun Cong's FC-31 team either given his own public statements. At least in the short term. However they were apparently given the go ahead to continue their own work.
I think there are multiple parallel design efforts inside Shenyang proper. Or it could even be, horror, that the Chinese government decided to purchase the MiG-29K or something ridiculous like that. That would also fit the rumors. But it seems kind of unlikely.
