Apparently, Gotham City Impostors was imposing a game that wasn't going to get delayed the whole time. It would seem that perhaps the beta that ran last month highlighted some areas that are going require more work. No word on what they are, but the delay is only supposed to be until next month. However, there is not a firmer date than "next month." Sorry. I'm sure crazy batmen fighting with real guns against equally crazy jokers also fighting with real guns is something large swaths of the nerdosphere were (rightly so) drooling over.
