The more time that is spent the less are the chances that India will actually buy the Rafale
FACTS:
India has signed the IGA with France
IAF wants Rafale
Now for the fact 1, the IGA is signed but the prices are more critical, the deal cannot be signed if the prices are not confirmed. At US$ 230 million a plane, the present govt is committing a political suicide, specially the argument would be that when 5th Gen was offered cheaply why did the govt go for 4th Gen plane? Rafale is not a 5th Gen plane and adding few tech will not make it 5th Gen.
About Fact 2: IAF, a lot of water has passed the bridge, Even if the Deal is signed now, the plane would not be available for the next 3 years at least and the entire 36 planes would come after maybe 7-8 years. In those 8 years the Tejas that IAF has ordered will start coming at at least 16 per year from year 2018-19 so 8 year from now, we could have 80 Tejas in the IAF and more being produced, that does solve the critical problem that IAF talks of .. NUMBERS. The cost of these planes is abt 40 milion a plane, and hence brings the benefit of price, cost and also confidence to the indian manufacturing industry.. Rafale deal would not bring any Technology for the industry to learn as its without any Technology transfer. Where as FGFA deal will come with tech transfer.
By the way, even if we go for FGFA, we shall be first testing the PAKFA and giving our inputs and then those will be incorporated, thus the first production aircraft for FGFA will start production 2 years later.
France has already lost the chance to clinch the deal, and now its upto the Russians to lose the deal.
