Yesterday Dienekes had a post up, Homo erectus soloensis fades into the past…. In it he states:

Every year or so there seems to be a redating of a key fossil in human evolution. It’s nice to see scientific self-correction in action, and soon after Neandertals got a little older, casting doubt on their supposedly long co-existence with modern humans, we now have a redating of Homo erectus soloensis from Java to about 150-550 thousand years ago, but certainly long before there were any anatomically modern humans in the area.

I think Dienekes is jumping the gun a bit in terms of the solidity of any given finding in knocking down prior consensus. That being said, the very young ages for Southeast Asian H. erectus, on the order of ~30-50,000 years B.P., always seemed strange to me. The paper Dienekes is referring to, The Age of the 20 Meter Solo River Terrace, Java, Indonesia and the Survival of Homo erectus in Asia, is rather technical in the earth science, as it involves dating and interpreting confounds in the stratigraphy. But this section of the discussion gets to the gist of the matter if you can’t follow the ...
