I think the test pilot is also guessing only. He think 2D vector based on his opinion. Surely, J-20 will get thrust vector but 2D or 3D is the question.

2D is bulky and limited vector angle. 3D is less stealthy but gives great all angle moves and less weight penalty.

Indeed ... as you know I cannot read Chinese, but here is a kind summary from "taxiya" at the SDF:

Brief translation:
ifeng: In your opinion, what kind of TVC should J-20 have?
Li Gang: 2D TVC works like this. (demonstrating with his hands).

My observation:
  1. It is ifeng reporter, not CCTV reporter.
  2. The video belongs to "Xiao Yang Shi Pin", a youtube like video platform operated by CCTV. It does not belong to any CCTV official channel. Therefor this reporter is more like a "Self Media".
  3. Apperantly Li Gang's words were cut out from a full sentence. So he might not even talk about J-20's TVC. He might not even talk to the ifeng reporter.
  4. Even he was interviewed by this ifeng reporter, he did not say anything about J-20, not shown by the video at least.
My conclusion is, there is no value in this video. From the way the video is cut, I highly suspect that the ifeng reporter is deliberately fabricating 2D TVC using Li Gang's position. A very common practice by "Self Media".
By the way ... I know this image if far from conclusive and also unconfirmed but anyway, this J-20A was allegedly spotted at Anshan, home of the #PLAAF's 1st Air Brigade.
As it seems the first J-20A with 61x2x serial number was spotted in January at CAC and the first J-20 at Anshan was noted via a satellite image in April.

Hey Deino, do you have the satellite image handy?

An interesting formation flight of six J-20 and one JL-10A trainer was seen today over Quzhou. Are the rehearsing for a flyby for the CCP centennial celebration on 23 July?

During the PRC National Defense Ministry’s monthly press conference for January 2021, the ministry’s spokesman was asked whether the J-20 was being fielded on a large scale.3 The spokesman’s response emphasized the “objective laws” governing the research and development of an aircraft and the progressive testing that the J-20 has undergone. 4 In effect, he answered negatively, but having another aviation brigade transition to the J-20 would suggest that his answer was not alluding to problems with the J-20. On the contrary, it would suggest that the PLAAF is satisfied with, and confident in, the capabilities of the J-20, and that more combat units are likely to receive the J-20 in the future.

Indeed ... that's the image I know since early April:

So finally there is confirmation that the PLAAF's 1st Air Brigade based at Anshan, Northern Theater Command is getting J-20As.

Revealed by @roderick_s_lee via a satellite image taken in early April and published by @CASI_Research.
Even more there are images available but not published yet taken at CAC in January clearly showing at least one J-20A using WS-10C engines spotting a 61x2x serial number.

How many jets are there in one Chinese brigade @Deino

I thought the 3D was decided in favor over the 2D TVC a long time ago? The only reason for 2D would be RCS improvements on the tail although serrated nozzles should be good enough already.
