Just wondering if the new planes of China like the J-10B/C or the J-16 will come with some form of sensor fusion.
All aircraft can be said to come with some form of sensor fusion. Sensor fusion is one of those buzz words which doesn't exactly have an explicit measurable threshold that one can say "yep, this is where sensor fusion begins".
The way "sensor fusion" is used these days though, is generally to refer to the threshold first pioneered by 5th generation fighters and advanced 4+ generation fighters, though I think it is pretty debatable if such a broad sweep of aircraft's degree of "sensor fusion" is of any use as a threshold or metric.
For your question about J-10B/C and J-16 etc, yes it can be safely assumed and indeed it has been rumoured that certain aspects of 5th generation avionics are likely to be present in their avionics suite, including but not limited to greater fusion of sensors to decrease the pilot's workload and to provide greater situational awareness.
Whether it meets whatever "sensor fusion" marketing term that some defence companies like to push out is another matter, considering we'll never know and never be able to compare the true degree of sensor fusion between their respective products.
