I agree that the J-10 isn't original, but I still like it. Most of the J-12 concept drawings look like... guess what... a ripped off FA-22 (loosely).
Back to the J-10... It isn't exactly like the Lavi, but it's really close. The first J-10 design was basically exactly like the Lavi. There are minor structural differences in the latest version. Like CAG said, it looks like the Lavi (albeit extended a little) with an Su-27's nose and Eurofighter canards. However, I remember reading somewhere that Israel had supposedly given China information from the Lavi prototypes.

I didn't mean to mislead you by saying the J-10 has the most hardpoints ever, because it doesn't. When I found out the amount though, I was slightly surprised, because I hadn't thought of it as a very large aircraft, and it's not (no official dimensions released, but use some common sense and compare sizes in pictures.)
Also, IAI reported that the Lavi outperformed F-16 in nearly all areas (even though they eventually cancelled it). Last time I checked,that was a good thing for a new aircraft to outperform an older one.
Also, The J-10 will enter service next year... I was a little off when I said in the process of entering service.
The only thing I can guarantee is that either the blue camo J-10 prototypes have either been repainted in some of the official PLAAF colors (check out sinodefence.com), or that the Chinese have started producing the J-10 in limited quantities. I suspect that the latter is true, since I have seen a picture at Jane's of 4 or more J-10s on the same flight line 9sinodefence has the paint shceme chart if you want to know which colors are the official PLAAF colors, etc.).
I think we are a little off on the point here though. This topic is about the J-12/ J-XX/ XXJ/ J-13, or whatever it is called. I just want anything anyone has on it, which obviously isn't much. I however, favor the design that looks like FA's X-32 ASTOVL. I think it looks better and it is more distinct than the FA-22. My opinion however, doesn't affect aerodynamics and performance, so we'll just have to wait a few years and see what turns up.
All I have found so far are blurry pictures of models, concept diagrams, and small mock-ups
