Tahnks for posting the pictures ... The point of interest IMO is, when will they ran-out of AL-31FN from Russia and will they introduce a WS-10A-equipped J-10A+ as an intermediate step before the J-10B reaches the regiments ??? ...
How many Russian AL-31FN's do they still have on their stocks ??
... any rumors about a possible location / regiment ??
... and finally...all single seaters are numberes staring with a 5-20/5-22/5-24 and the twin seater with a 2- ... could that be the number of the production block ?? ... I remember Huitong said the forth block switched to the slightly improved J-10A !?

It's just speculation but J10A production may end even before the AL-31FN
inventory runs out. The last batch of 200 engines was procured within 2008-09 timeframe if I remember correctly. As we haven't seen any new J10A regiment forming for a while, we can safely assume the new planes in question get their engines from the latest order.
On the other hand, J10B has been under flight test for over a year now without any major drama, and will likely get certified at the year-end. Meanwhile the production line at CAC needs to be modified in preparation for J10B's batch production next year, I would say the production of J10A should end before the upgrade of factory facilities starts.
Now that there are bound to be extra AL-31FN engines (even we use 1:2 spare engine ratio for existing J10A fleet), the first batch of J10Bs may use them in stead of the intended FWS10 engine, which has got J11 series on the top of the customer list.
