[Ed. note]: As of about 9:00 EST, Kotaku has corrected their error.
According to Kotaku’s story today on Ghostbusters DS, the next-gen versions of the game will not feature Bill Murray’s classic wisecracker Peter Venkman. It seems that the DS version will have him though, because there is no voice-acting in that version. This stands in stark contrast to Kotaku’s earlier story about Bill Murray enjoying recording his game dialogue so much he would actually consider a third movie.
In fact, Murray himself has appeared on Conan O’Brien and the Today Show talking about the voice work that he has already put in the can. I’m thinking this is a blown call by the big K, and we can expect to see and hear Dr. Venkman in due course.
[Edit: Check out this trailer that clearly features Bill Murray.]
