Similarly, I expect KFX, TFX, AMCA, and F-3 if it gets built, to end up as more "late 5th generation fighters" or perhaps "5+" generation fighters.
Don't know about TFX or AMCA but the KFX is already backing out of the fifth generation game. According to the Korean developers, they'll be reducing the technological difficulty by forgoing the weaponsbay and carrying the load externally. When the news broke, Indonesia stated that they will back out of the project and there is speculation that the Indonesians may collaborate with the SAC on the FC-31 instead.
Also, there are rumors on Chines forums regarding how South Koreans tried to steal FC-31 related technology through Chinese channels in Shenyang. Pretty funny considering the design similarities between the FC-31 and the revised KF-X model with conventional configuration.
