I remember @MastanKhan saying this a long time ago....if the US realises that you already possess a piece of technology, they will not hesitate to sell it to you...case in point is AESA radar....we will be getting AESA techonology in the form of Block 3 therefore the willingness of the Americans...
Wasnt Allah Nazar dead already.....am sure i read the news about his death here on PDF...the news said he was killed in an operation near Awaran...not sure about the exact date though....
I still feel we should keep our abilities classified....giving ur enemy an idea about ur strength will provide him with the techniques to counter ur strength
Wont that put us at a disadvantage....i mean the Indians are arming Rafales with Meteor which means they will have an idea about the BVRAAM Block 3 is going to field...
I too am not expecting any revolutionary changes as you mentioned but incorporating three axis FBW is going to change the vertical stabilizer and the frontal nose will have to be modified in order to incorporate an AESA in it.
