The Indian Airforce chief has recently stated that they plans to induct the FGFA / PAK-FA as 166 single-seaters and 48 twin-seaters
I have also read that they plan to aquire more one-seaters.
Makes sense, because they have enough Su-30s and other non-stealth planes to act as bombers (once the enemy threat has been cleared), and would use the stealth fighters in the air superiority role, with possible single strikes on SAM and radar installations and other defended high value targets, in the opening phase of a hypothetical war.
From the interview what i can make out is they are planning to use RVV-MD and RVV-SD as A2A missile for PAK-FA but from what i have read before PAK-FA will have a new class of A2A missile , Id 300 as WVR and BVR missile will be Ramjet R-77 and R-77M.
The plane in the picture does not exist, it is a photoshop/concept art. The concept art is based on the Berkut Su-47 technology demonstrator, but has several differences (engine nacelles being the most obvious).
