The problem with fighting twisting is the reason production Su-47's will have a more conventional wing. Sukhoi came to con conclusion we did with our X-29: They have the materials and can make it work well, but the maintanence and cost associated are not worth the gains.
As for missiles: Current Archers are a fair match for the 9X in off-bore capability, and R77 development is roughly paralleling the AMRAAM. I would not be at all surprised when both eastern and western 'long sticks' are released in ramjet versions at the same time. (FMRAAM vs R77M1)
Look, I'm not ripping Russian equipment, but honestly, it's not a matter of who produces better equipment or who's scientists are smarter - it's a matter of money and time. I'm willing to bet that just the R&D budget for the United States Air Force is comparable (if not more) to the entire military budget of the Russian military forces. The Americans have that luxury, and it cannot be denied.
For example, the R-73/M1 was ahead of its time when it entered service, but it virtually hasn't changed at all since the collapse of the Soviet Union. It's seeker technology is comparable to the AIM-9L/M, not the AIM-9X - in that, it's not even close. Same with the AIM-120 and R-77 comparison; let's just say that the latter shouldn't even be considered to be in service with the Russian military considering how little of them are produced.
The AIM-120, meanwhile, is in widespread use in around 20 different countries, and have been upgraded ever since it's IOC. IMO, the R-77 is comparable to the AIM-120A, but against the AIM-120B/C, the only thing the R-77 has against them is it's fantastic agility (which means nothing if you don't have smart computers and a good seeker to exploit it to its full).
