Warner Bros To Announce New Batman Title On December 31st?

Warner Bros has made a teaser post on their official Facebook page, asking all their fans to keep their eyes peeled for a special announcement, that will be made on December 31st. Honestly, we have no clue as to what this may be about, we here are some calculated speculations.

WB wouldn't make such a big deal out of this if it were a DLC for Batman: Arkham Origins. We believe that a next-gen version of the game will be announced on the calendar marked date. Ready for a Batman: Arkham Origins "Definitive" edition?
