Nowhere in that article did it mention that Publisher X will publish Ghostbusters: The Video Game. I'm very familiar with the company and I can almost guarantee they will not be publishing Ghostbusters, as Publisher X does not publish games that make it to the physical retail space.

Since the RedFly version of Ghostbusters is Nintendo DS, PS2, and Wii (not WiiWare), Publisher X will (most likely) not publish the title.
