Not sure why this much gloom and doom, especially from BR Oldies.
OK, to be very brief:
1) From the Geek at Large Saurav Jha. Dated Dec, 2014, so not that old:A note on India's Advanced Medium Combat Aircraft (AMCA) project
1 wrote:India meanwhile is still haggling with Russia on work share and tech share issues before it inks the final development contract for the Fifth Generation Fighter Aircraft (FGFA) that will be based on the Sukhoi T-50 PAK-FA baseline. Regardless, it has been clear for some time now that India will have to mount a serious fifth generation effort of its own in order to both free itself from dependency on any other country as well build its aerospace sector on the foundation created through the Light Combat Aircraft (LCA) program. For that purpose the Aeronautical Development Agency (ADA) that oversees the LCA program has now increased the pace of activity with respect to the Advanced Medium Combat Aircraft (AMCA) program. However for the AMCA to reach fruition in a timely manner, the government of the day would do well to invest more in creating deeper aerospace development infrastructure.

3 wrote:"The RFPs will be sent out by April 2015, and in another eight months we will firm up our choice of engine to power the AMCA," says Dr Tamilmani. "We however have to do a lot work on our own to develop thrust vectoring for the AMCA," he adds.
That hardly is waiting for something to happen.
It seems that the AMCA will also have an unusually large internal weapons bay that will have the capacity to accommodate around three tons worth of weapons.
Hardly stuff that is unthought about.
Then, there is a newer news item:June, 2015 :: Carter to face Indian demand for engine technology
But India wants cutting-edge. Defence ministry sources say they want GE to partner the DRDO in upgrading the F-414 to deliver 110 KN of peak power to the AMCA, allowing its twin-engines to deliver 220 KN of peak power to the fighter.
GE is sees enormous commercial benefits in this co-development, which would capture the engine market for 200 Tejas and 200 AMCA. Since a fighter engine's life is about 1,500 hours and the aircraft itself lasts 5,000-6,000 hours, each fighter consumes 3.5 engines during its service life. GE is looking at supplying 700 engines for the Tejas and 1,400 for the AMCA over their service lives.
Yet, developing an advanced F-414 engine in India would require GE to part with valuable technologies, particularly in the high-melting-point alloys that make the combustion chamber. Engine designers say an output of 90 KN requires the combustion chamber to be built of materials that withstand temperatures of 1,800 degrees Kelvin. Achieving engine output of 110 KN would generate 2,000 degrees Kelvin in the combustion chamber. Washington remains reluctant to share these technologies, even after committing to jointly exploring cooperation.
"The DTTI should facilitate US permissions, especially with a working group in place for engine technology. But we are getting signals this may not happen," says a top DRDO scientist.
Long way to go, but, again, in the spirit of THIS thread, I do not see an Albatross. Neither a turkey. I see HUGE risks, but none that cannot be overcome.
