Frankly speaking... I really doubt that news. First off... other than the Russian, who is the Indian going to turn to when they wanted to buy state of the art fighters at the price per unit as offered by the Russian. Second off, where is the Indian going to get the spare parts and stuff (such as munition) for their large fleet of Russian aircrafts and systems. So why would the Russian actually mind too much as to whether the Indians are going to be too happy or not.
Also, if I was the Russian, I would have sell as much RD-93 as I can to the Pakistani or Chinese before the WS-13 came online. Because I know that the WS-13 will ultimately replace the RD-93... and I will not be able to sell anymore of this engine anymore once the WS-13 came about and that will reduce my revenue. In actual fact, I will even be pouring R&D monies into replacement or upgrades for my RD-93, so that I can have an engine that was better (and hopefully cheaper) than the WS-13 and continue to sell this new engines as a alternative to the Pakistani and other countries who wanted the JF-17.
