It's because of your doubt this isn't going to happen.
PURGE THE DOUBT OR THE DREAM IS DEAD!
Just because I'm not hype doesn't mean I doubt it will happen.
I'm sure Sega has something to show off at TGS, I just don't know if it will be good is all.
It'll probably be good. Hatsune Miku vs Jack Lumber: Battle of Destiny. I would play the SHIT out of that game.
EDIT: The thought that it might be PS4 AND PC makes me a bit more hype, because I might actually be able to play it then. Whatever it is.
EDIT II: I can't say what the game will be, but I think we need to wait and see
