I think the possibilty that china has indigenised the J-11 and doesnt need the russians anymore is a lot more credible than the rest. Think about it. The guys have been chasin all over the globe for this aircraft during the entire 1990s and go to the length of gettin co production rights, upgrade packages and later variants and lets not forget, constantly trying to integrate its arsenal on these fighters. The WS-10, the new radar, the recently cracked source code it all makes sense to me. All they need to do now is to make their own variants and improvements but i dont think any of this is happening soon as the chinese need the rest of the russian arms unless they decide to count on the french lifting the arms embargoe:idea2
