Will pakistan cancel JF-17?

I have been hearing this rumour - that pakistan will cancel the JF-17 in favour of the F16 purchase from the US (although china is also wanting them to cancel the JF-17 and buy the J-10)


now , say they do - would Iran or Syria become another buyer option? as the production lines are up and running - a cancelled order would mean alot of spare capacity and if china want to off-load , there could be a very willing buyer in iran?


thoughts?
