That's not the point and no-one denies this, what however can strictly be denied are these fan-boy claims by some we will see it "within the next 15 months in PAF-colours", "Pakistan is involved in the current flight testing of the J-31 (in fact there is still none) or J-35" ... and "there are already several prototypes flying!"
This is simply ridiculous and ridiculing critics or skeptics doesn't make it more realistic. But as I said, let's wait and see - I'm sure we'll know more by November at the Zhuhai trade fair at the latest - and then I'm happy to accept some people's apologies for all the rubbish they loudly posted here.
Personally I think it is some wishful thinking mixed up with some realistic points to try and give the impression of some kind of insider knowledge.
Totally reasonable for PAF to have staff involved in testing the J-31 if the ACM is on record as saying we are inducting it, "next 15 month for induction" is however a bit of a big jump. I would expect it to be in PLAN service before PAF for sure.
