For the present, you are quite correct. However, if age-dating these finds reveals that the specimens were emplaced contemporaneously with surrounding sediments, then we will have to re-think our current theories.
This evidence suggests that it is possible that modern humans may have evolved in Asia. But the ancestors of that population could still have been African. Hence this doesn't not invalidate the genetic evidence that you cite.
Fact is, the Chinese are very political with their archeology, too. They are very nervous about the caucasian bones found in Western China, possibly because of the implications for autonomy in that region. The Chinese didn't properly date these remains when they discovered them. Now they are going back & saying they are much older. Who to believe?
