It's not about one thing adding "major" RCS values to the aircraft, but an accumulation of all the small things. This aircraft will soon face top-of-the-line American radars and one small change like that may spell life or death. What the J-20 engineers could do is to add a thin layer of gold to the insides that is similar to what is seen on the F-22. In fact, the J-20 may already have the gold, but nothing is confirmed:
Don't be a snott Eng, explain the vents to him, also explain what advantage may be had by the reshaped intakes?? for me and thanks again????
I do like the ventrical fins, and like the Eng stated they are quite necessary and contribute to the fine flying capabilities we observed on the earlier prototypes, and now we have an idea of why 2003 was delayed???
I love the very pronounced wash-out of the wing tips, it is a gorgeous airplane, and like the rest of you, yes I am impressed and excited! like I said the other day, I am simply amazed what you young gentlemen, particularly Dieno are able to deduce from photographs, I guess I'm going to have to look a little closer???

It's said to be F-35 alike EODAS.

It looks like they reduced the size of the actuators.

Yes, gold embedded canopies are known to be beneficial to RCS but how is that relevant to the fact that adding in a brace isn't going to kill the J-20s RCS?
F-35 has a one piece braced canopy. T-50 has a two piece canopy. Even the YF-23, generally accepted as an aircraft even stealthier than they've YF-22, had a two piece canopy.
I hope they retain the brace. It must be there for structural and/or safety reasons. Nor am I convinced it will add anything drastic to RCS returns. The gain should be worth the loss, if there is any of the latter.

Here's the best comparitive images I could find, from about the same angle.
The first is the new aircraft, the second is of the older. Yes, the intakes are shaped differently. Also, there looks to be some kind of new sensor under the nose there.
I cannot get a real good feel for it, but from this angle the front canards and the vertical stabilizors do not look that much different. The cockpit canopy does seem to have some minor differences too. But as you can also see, the lighting and angle make a difference on the color as perceived by the camera. I am not sure just yet, from these pictures alone, that the new aircraft is that much lighter.
The most obvious changes for what I can see are the intakes. Definitely a little more sharp, slightly smaller, and had an obvious "bump" there.
Well, I agree on the size and shape of the intakes. But if you mean by the "bump" the section there on the inside of the left intake,on the existing aircraft in a little different lighting, you can see that it exists there too...that is if we are talking about the same thing.
