Ivan:
Wouldn't the AN 225 possibly surpass the Boeing 747-800 and the Airbus 380 for the money? Which brings up another subject? I've heard about Russian superiority aircraft. How are they doing marketing their Migs and SUs?

An-255 is outsized loads only. It has more
effectively useable cargo space than the A380 and 747-800 only because there is no real passenger deck (actually they use the space created by extending the cockpit floor to the wing spar as passenger area). You can fit complete refinery towers in it if you need to.
Only point against it is that it needs a crew of 6 minimum (pilot, navigator, 2x flight engineer and two loadmasters) to operate legally (An-124 needs 5, one loadmaster less), and that the certification is somewhere beteeen experimental and production.
About the fighters
MiG is still done by Rosvoorouzhenie, but interest is dropping, even though Malaysia bought a few fresh-off-the-line MiG-29 with some minor improvements. Sukhoi is the main producer now, especially after what the USAF pulled off in the training against India.
Sukhoi is allowed some freedom in the sales stuff (cockpit outfitting on customer demands), and usually goes for license production as that gives them a more stable cashflow. Package deals are still done by Rosvoorouzhenie, as they usually include missiles and training stuff which Sukhoi is not allowed to do.
