So did we slapped ourselves in the mouth when back then we fiercely denied 2001 and 2002 to be demonstrators?
I don't quite understand why you'd assume the initial models to be tech demonstrators or why the airframe design would change so massively between the 2001/2002 and 2003 models.
For the type of performance testing the 2001/2002 models have done, there's no need to have that shape of airframe; the 2001/2002 models have never even been observed going supersonic.
We're assuming it because that's what the good ole rumour mill's been cooking up, for long enough that it's a prediction we've all internalized.
I'd hope not. I imagine that's the kind of thing PLAAF wouldn't want people to easily see... and preferably they'd do it at altitudes where people with DSLRs can't snap pictures of.
This picture shows various development milestones for jet engines within China. There is a discussion on certain Chinese forum as to which stage WS-15 is at right now.
