In the interest of containing this topic, please contain all of this discussion within Threadzilla. I'm not combining this post with that thread ... just scan through that thread, it's all in there.
The nutshell summary is that there is no official news, and there is an agreement between VW and CARB and the EPA to not disclose anything until there is an official plan to be made public. Anything and everything else that you may be hearing consists of idle speculation, lawyers threatening various things to boost their own cases, etc.
