What's up with the SU-34 (aka SU-32FN/SU-27IB/SU-27KM-2)?
Last time I checked there were only 3 aircraft built, have they built any more of those? Does the Russian Air Force have any in service? Any other news about this aircraft?
Anyways, let's face it, the S-37 and the MiG 1.44 will never be operational fighters. The SU-37 has more chances of entering service because it is based on a well established platform, and it can actually use weapons. But with Russia's financial situation even the SU-37 may never enter service.
