Pretty sure it's a new pic.
J16-1612
YES, and I would say its a serial aircraft 02 of Block 1 !

well, that one j11 with a testbed easa radar radome had a visibly shorter radome than other j11. once we start getting better images of j16 we will surely be able to compare to radome lengths and see for ourselves.
The engines don't look like AL-31. What are they? WS-10x?
That of course is assuming that J-11 testbed was testing an AESA for J-16 and not for a different other flanker variant (such as J-15 or retrofit J-11B)
