its disappointing to see china still not mass producing j20

Define mass production then ... mass production is a very ambiguous term
We do not have a good estimate of the number of J-20s produced at all ... and it is very difficult to accurately predict a number since we don't know what the PLAAF requirements are. Perhaps they only want limited numbers of J-20s before the WS-15 becomes available? IMO, this is very understandable. Why mass produce an obviously inferior version when a much better version is going to be available in the not too distant future. Of course, this might be wrong and the PLAAF wants to produce as many J-20s as possible right now to deal with the F-35 threat in the Pacific. But we cannot be sure.Mass production usually means in large numbers or up to the capacity. Chinese can easily produce 40+ J-20 each year.

First off, the engine is called the WS-15. Regarding your article, hopefully you are not referring to the one written by Minnie Chan, which is full of false information and contradictions.You might be correct, building in small batches and wait for WA-15 engine which will have more thrust than Russian engine but recent article suggest that J-20B is in mass production and WA-15 engine won’t be ready until 2022.
China has also increased the production of J-16s to make up the numbers to go against F-18s.

In my opinion, the WS-15 will most likely be fitted onto the J-20 relatively soon (currently its undergoing flight testing most likely aboard a J-11). But from then to mass production for the J-20B will take another couple years. In 2018, Dr. Liu Daxiang, former 624 Gas Turbine Institute director, said the WS-15 would receive design certification within 3 to 5 years, which translates to 2021 to 2023. Only after design certification can the WS-15 commence mass production. So until then, the PLAAF will have to make do with the Taihangs, offering around 140 kN of thrust.
All non credible ...yes, I was referring to Minnie Chan‘s article. There are also rumors that China is in talk with Russia to acquire large number of SU-35S.
Nothing really new but Pupu confirms that the WS-15 will come with 3D TVC on J-20B

The WS-15 is already conducting flight tests aboard a modified J-11 ... it shouldn't be long before it moves to the J-20 for testing, which I think is when we are going to get the pictures... but the question is: WHEN?

Well I think the PLAAF would only put the WS-15 as one of the engines, with the other one being the WS-10 for testing reasons but I would expect superior aerodynamic performance given this extra thrust (albeit I don't think the speed would increase too much given the flanker's design as you mentioned). Regarding Wikipedia's Mach 2.4 claim, I don't think that has any basis. The J-20 is not a dedicated interceptor so why would it need to fly so fast?J-11 powered by 40,000lb engine, do you think its top speed will increase apart from fast acceleration with extra 10,000lb per engine? The SU-35 maximum speed is the same as standard Su-27, probably the design doesn't allow it any faster. J-20 with less frontal surface could go Mach 2.5 if the specification on Wikipedia is correct
USAF veteran. F-111 Cold War, then F-16 Desert Storm.Do you work in aerospace?
In order of accomplishments: Good => Excellent => Outstanding.How is j20 in your opinion?
Wouldn't transition from F-111 to F-15 have made more sense?USAF veteran. F-111 Cold War, then F-16 Desert Storm.
