It's not clear how much information is going to be released. There was this not too long ago:
http://www.telegraph.co.uk/news/worldnew...h-clean-up.html"Chinese officials have instructed the media not to sensationalise the accident, and fresh instructions sent to reporters yesterday said: "Do not report the accident too frequently. Report moving stories about people donating blood or taxi drivers not taking fares from victims. Do not investigate the cause of the accident."
