The ROK (South Korea) is looking at fielding its own advanced combat aircraft (Paid Subscription Required), EADS is pushing a Typhoon pushed somewhere past tranche 3, and SAAB is pushing a new stealth supercruiser, Boeing is pitching a significantly updated F-15, while Lockheed-Martin is pitching the F-35.

This is in parallel to the (IMHO overambitious) indiginous KFX stealth fighter program.

SAAB is proposing both a one and a two engine variant.

Honestly, the only two I see likely are the F-35 and Boeing’s proposal. The former because it is the 800 lb gorilla in the room, and the latter because they are currently taking shipments of the F-15K.

Note that in the competition that selected the F-15K, the Rafale was widely rumored to have won, but the fact that it was not a US product led to the selection of the Eagle.
