We've had mock-ups of a JH-XX being posted repeatedly, mostly showing a twin-engined design with v-tails that is at least as large as the J-20, probably larger.

We can also assume that the JH-XX is going to be stealthier than the J-20 for the reasons I've listed above (a fighter bomber doesn't need the same strong aerodynamic characteristics as an air superiority fighter), as well as from a lookover of the various mock-ups' aerodynamic design. The swept wing, certainly, does no favors for its stealth, especially its rear stealth, but generally in terms of wings and angles, it is closer to the Checkmate and YF-23, with a V-tail and no tail elevators or canards, and for that matter, no ventral fins.

Likewise, from the SAC leak, it seems reasonable to assume the radar will be comparably large as the Su-34's radar, which is significantly larger than that on the J-20.

Or, in other words, according to American conceptions of what 5th and 6th generation aircraft should look like, the JH-XX is a better stealth fighter than the J-20, with a combination of careful shaping, and powerful radar.

Your arguments always make too many assumptions that you speak of as if they are widely accepted or consensus understanding, it makes any sort of attempt of a constructive discussion with you immensely difficult.

Other people might have the energy to engage on those terms, but I do not.

In this case, I am not sure what that black and white picture even shows, if it is even meant to represent an aircraft, so I am deliberately choosing to not make any comment about what it is or whether it may be JH-XX or what JH-XX may look like, because sometimes saying nothing is the best choice for everyone at large.

The assumption you're making is that the J-20 is a strong or perfect stealth platform, when it clearly makes choices that compromise stealth for aerodynamics. The J-20's canards, contrary to claims, are not coplanar with the opposite wing. While the ventral fins are semi-coplanar with the tailfins, they are only semi-coplanar, sharing an angle but not the same plane with the tailfins.

Moreover, the canards themselves have a visible gap with the main body, creating a corner reflector that has to be assiduously treated with RAM, and themselves provide an emitter that reflects into all sorts of weird angles into the main wing and the tailfins. The same corner reflector exists in the F-22., but the corner reflector is concealed by the main wing. On the F-35, the tails are connected from the rear, so if a corner reflector exists it's effective from the rear and the sides, which is hard to exploit.

And IIRC, Chinese military commentators have commented that when it comes to radar stealth, the J-20 hopes to use its superior radar to compensate for higher RCS than adversary aircraft.

In comparison, the JH-XX's only compromise (taken from various models, artist's depictions, etc) from what is considered a pure stealth shaping design utilizing V-tails is the swept wings, which may cause back scatter to move toward the V-tails and thus reflect toward the radar sending out the signal.

1. I don't know where you are getting that assumption from.
2. Even if I did hold that position (which I do not), that has no bearing on the fact it is incorrect for us to talk so much about JH-XX at this stage when that picture could literally be anything or nothing.

Even extrapolating from that, the only thing that can be ascertained with anything resembling mild confidence is that it may have side by side seating, and it's meant to be somewhat stealthy.

Anything else beyond that is being either dishonest or massively jumping the gun.

you are correct, the only thing to know from the pic is that China potentially has two stealth bombers in development, since it is generally accepted that there is a bigger one being worked on in Xi'an. it would be pretty insane if China were to deploy both.
