I was looking to my books, the front end (nose, inlet) of that striking bird, looks like the Boeing proposal to the ATF contest, unfortunately i can post the image now, but i will). The rear end is clearly a MIg 1.42, wide spaced verticals with fins. So, if it is true, the designers can't claim any copyright. It is a mix of older designs. Just like the J-8, just like the J-10 just like anything those guys have produced.
I can't see if this beast is single or twin engined. Judging from the size i bet it is a 2 engined. Well that particular inlet configuration has a drawback in that in case of one engine flame out, the other will be directly affected. Very risky configuration, and one of the reasons USAF validated Boeing's proposal low. As a friend would say, "just my two cents!"
