VGChartz obviously never made up for their undertracking of the PS4. It's definitely worth bringing that up, as it is a failure on the part of the site.
As for the Chinese numbers... Good question. lol
VGC definitely don't have much credibility, especially failing to respond properly to -actual- direct information from Sony. So we ought to take their guesses with a large grain of salt. As far as I can tell, though, VGC are basically their own source on the Chinese numbers.
As for PS4 in China, that hasn't happened yet. We can expect it to be the leading console there, though.
