A lot has happened since Oct 2016, especially with Tejas. And it has been largely positive for the Tejas, with the exception of that fake news article on the bird. Social media and the 24 hour news cycle has largely helped the Tejas cause. The IAF is slowly, but surely, walking up to the idea that SEF will take a LONG time to come to fruition. Time is not a luxury that the IAF has. The IAF has also realized that the Tejas is the *SINGLE* engine bird that is available right now.
Delay in the SEF is also delivering in other areas. The news reports of the revival of the Jaguar re-engine program, another Tejas line investment (in the tune of ~ Rs 1300 crore = $200 million USD), the first step in the confirmed order of the 83 Mk1As, the possible (still need official confirmation) revival of Mk2 development are steps in the right direction. The Super Sukhoi upgrade, the MiG-29 upgrade, the Mirage 2000 (stalled for now) upgrade are also all good developments as well. SEF may still happen, but it will follow all the MoD procedures and take its own sweet time. And at that point, SEF will likely be pointless.
