I really don't care what other aircraft they put into FC4 as long as it has a single 4th Gen Russian Jet (FC level), then its good. MiG-29K looks a nice candidate and so is the Su-30 (maybe not Su-30 as its dual-seat). I mean they had the MiG-29K already in the original Su-27 Commander versions and I believe there are remnants of the MiG-29K code still available in some lua file in the game. Come on, just slap on the MiG-29 PFM they are currently working on, add Su-25T weapons capability, some fancy MFDs, and a working hook from the Su-33 and voila MiG-29K..:D (Long shot, I know, but I got to try)
