How could any of us here know the answers to such questions? It is possible that new variants have them? Sure. Is it probable? There's no way of knowing. Every person could give you their guess and that's about it. Personally, I'd say the fighter mission requirements may prevent the DSI intakes solution, as those, at least to my knowledge, don't work that well past a certain mach number, which seems to be around 1.6 or 1.7. On the other hand, if technology and budget permits, some degree of supercruising seems quite likely for some future variant of J-10.
