I think nowhere he said that it will have new engine(s). However, he did talked about enhanced range, that could mean improved engine version. He talked about Pakistan own's control on avionics, EW systems and other components. That's exactly what many were suspecting.
Also, Important point is he never mentioned dual engines. More than likely its JF-17 with improved engine and home grown avionics and technologies. That's exactly what I get from air commodore talk.
I think this report clarifies now what JF-17 PFX is. Don't have to look at graphics at all, We know they mix up everything up, sometimes they are showing JF-17 with some enhanced design and sometimes they are showing dual engine stealth aircraft. It is obvious that Pakistan is not making a dual engine 5th gen fighter otherwise why going for J-31/35. Its straight forward that its a single engine 4.5+ aircraft. Slight bit of design enhancements on JF-17, improved engine and home grown avionics. That's all.
Let's recap what Air commodore exactly said:
- 4.5+ Generation
- Difficult to detect ( Could be radar absorbing coating or reduced RCS but not necessarily, It could be only reduced infrared, electromagnetic signatures as he specifically referred to radar / sensors to detect enemy without transmitting anything)
- Pakistan's own control / production on radars / avionics (Home grown Radars / Avionics)
- Home grown EW and other systems
- First flight in 5 to 6 years.
This paints me a picture of JF-17 localized version.
IMO, a good step in right direction. Critical step for indigenization. Can't go for unrealistic goals right away. Another important part is i think PAF is also considering MLU for a massive Jf-17 fleet of PAF. This program looks like is designed to facilitate that as well with the installation of localized radars / EW systems of PFX to be used in rest of JF-17 feet (block 1 & 2s) after a decade or so. It will make no sense if PAF invests separately and develop different radars / EWs for MLU of massive PAF JF-17 fleet.
