The general rule of thumb will be that the new management will scrap that plan and create their own. That's what management does. :-)
Last I saw published they were talking late 2013 for release of the new model Octavia in Australia with the vRS after that. I guess it depends when RHD production starts and when they get Australian ADR compliance organised. At least the RHD side of things will be answered when new Octavias hit the UK.
