Rather Uninspired Ghostbusters Poster Incites Inspired Overspeculation

Say you were at Wondercon this past weekend and saw this:
Would you nerd-gasm in joy? Would you be certain that this couldn’t refer to the previously announced Ghostbusters video game, because there’s no way someone would tease an existing product? Would you be certain that this poster is heralding nothing less than a third Ghostbusters movie, perhaps one in CG? Would you freak out on the internet? All signs point to yes, you would.

At any rate, took the pic above, which is causing internet madness even as I type. Frankly, I think a new Ghostbusters film?even a CG one?could afford a better marketing plan than a nondescript poster, and this likely refers to new merchandise, a new comic, or the video game.
