Just looks like mere speculation - what others are doing

Sancho did you read my assumption-what do you think
Hi Prateek, see I don't havy any doubts about the capabilities of Russian engineers and I know that things like radar blockers...can be added and will most likely.
The 3D coaxial labyrinth radar blocker for example sounds very interesting and more advanced than those used from Boeing (check the video posted by ptldM3) and I wonder if something like this would be possible.
The big problem is that the project is only at it's early stage and nobody can say what is to come, but imo still a looooooot of work is still to do especially in terms of stealth. Of course they can make ducted air intakes, even the Su 47 Berkut has them and exactly that fighter is the yardstick with what I am comparing Pak Fa, not like others with the US F22, F35..., because we saw at Su 47 what the Russians could do, so I expected more than that from Pak Fa of course.
At the moment, allthough I find the Pak Fa prototypes very promising, the stealth features (as far as we can tell) are not really impressive!
For example the rounded engine covers like normal Flankers, the internal weapon bay, that is not on a level with the engine bottom sides, compare that to Su 47:
One smooth level, if the sides of the air intake and fuselage would be angled, it would be clearly better in terms of stealth design right?
We also can compare the difference in engine and weapon bay positions, because Pak Fa uses the space between the engines for weapons, just like the Flankers used before. Su 47 instead had both engines directly besides each other and the weapon bay in front of them, which made a better duct for the air intakes possible.
So good internal weapon bay and ducted air intake design is nothing that the Russians can't do, but it is surprising to me that Pak Fa used this way and is not more based of the Su 47.
My guess is still, that the final Pak Fa version will have a different fuselage design and most likely 2 internal weapon bays, that can be used also as 1, for longer A2G missiles like Kh 35, Kh 58, or even a smaller version of Brahmos. Also a better stealth designed fuselage, a ducted air intake, or something like the 3D radar blocker.
We must keep in mind the huge size of Pak Fa, so stealth, to avoid radar detection must be a major point without any compromise!
