Haha wow, yeah, why am I not surprised? This thing has been in development hell for so long that it's best to take any news of it moving forward with a grain of salt.
And yeah, I have the game too and it was quite decent. I do hope they make a sequel to that and expand upon the gameplay a bit. It was quite satisfying, but I kind of wished it were more open-ended. I'd love for them to make an open-ended game where you drive the Ecto-1 throughout NYC. Sort of like a supernatural GTA.
