No, I don't. Hey, they might be funding Gundams or Death Stars, right? You don't think so? Why? Do you know line by line what they're funding? No? Then they might! We "don't know." LOL Do you have evidence that flying bears don't exist? No? Then they might exist, right? We are at the point where if you can't prove that something doesn't exist, then we're 50/50 on whether it exists, aren't we?
Facts are here:
J-20: First flight 2011, immediately bears PLAAF star, publicly funded by PLAAF, 8 prototypes built in 5 years, enters LRIP 2016.
J-31: First flight 2012; it is 2018 and there are 2 prototypes, none with PLAAF/PLAN markings, no public endorsements. No evidence or reason for secret funding either.
To me, that looks like no interest. If anybody here thinks that looks promising, cool. I'm not on that boat.
