I agree with what OP is saying... since there was a similar experience with FF13... too much info was being given to people, that they just literally stopped caring about the game. If less information was given out, then people would have anticipated, and actually wanted the game for themselves, instead of being told about almost everything in the game.
Sure, getting more information is great, but I think Treyarch has put out enough info. Maybe a small preview before Halloween, and that should be it.
Just imo stuff
