The Beetle sedan will be at the Sydney Motor Show, which starts on Friday. VW Australia has borrowed some vintage VW DVDs from Club Veedub to help with the launch. Yes it's supposed to be released in February. It will only be a niche model; VWA's priority at the moment is launching the Up!, which will be a much bigger seller. The Cabrio has not yet gone on sale overseas, so it probably won't make it here before the end of 2013.
