Is VW “Thunderbunny” for real?

Last November’s SEMA show featured a Volkswagen "Thunderbunny" concept car, prompting a hash of reactions to a post-R32 edition.
According to a VW fanblog, UK MkIVs, the Golf RS was on display at a VW corporate event. Insiders say that the RS will see a limited production run of 500-900 models, with it debuting on either the Frankfurt or Essen car shows later this year.
Speculation on whether this could be the "R36" abound.
Watch out for more details.
