It doesn't carry enough gas to go around the block.
I think this plane has been shelved.
There are also some reports from the Indians that:
1) The canard wing has been scrapped in favor of a standard planform to reduce production costs/complexity.
2) The date that the Russians were originally using for production was 2009, not 2007.
3) The Russians were also talking about possible funding constraints in this project. (Priorities went to commercial aircraft development.)
Sounds to me like the good General has got himself a nifty new fighter that got its budget chopped, so he's shopping it around to the Indians to get THEM to "build it under license". (Actually to fund and finish up the project for the Reds.)
Looks like a hot ride, but the size (70,000+ lb), lack of aerial refuel and rest of the configuration shown in your picture would limit the bird to VERY long, well-maintained runways and a high speed/high altitude/maybe 200 mile radius interceptor role.
How it would do as a dogfighter with the standard swept wing and all that weight............
The swept-forward wings look like what NASA was doing a few years ago for high mobility jets, but which was abandoned.
We consentrated on speed, instead.
Hey dude! The wings are on backwards man!
