I think future of the 29 is dependent more on MRCA than any of the other competitors. F16,FA18,Phoon, Gripen are all pretty much assured to be in service up to 2030 (or longer) with significant numbers to warrent continuig support and upgrade program.
Same cant be said for Fulcrum. Few dozen Ks will not be enough to warrant significant expenditure and upgrade program. 120 Aircraft filled with latest tech (AESA , OLS, Jammers etc) would change that. There are many Mig29 opperators in the wolrd with units which are mostly at or beyond their service life. Some of these looking for replacement could look to Fulcrum again, providing that its future is secured.
I expect MiG to be pushing very hard for MRCA as it stands most to gain/lose compared to other manifacturers. Question is whether or not internal politicis in Russia is such that some "players' would like MiG to remain weak??
