Lego officially announced an Ecto-1 (presumably with 4 Ghostbusters Lego people) set during their Fall 2013 Lego Cuusoo review.
Its too early to know details about this upcoming set. It would be great (not a deal breaker) if you could also build Ecto-1A. Which could be similar to how the DeLorean set can be made into either of the three versions from the Back To The Future trilogy.
