i know arkham city came out a long time ago and there are many easter eggs for an arkham 3 game
and many more but the one that caught my eye is what a undercover cop said in the iceberg lounge: this what next, all out war in gotham.
could this be a hint at arkham 3
then i heard a prisoner saying: when we get out gotham will burn.
and other things like that so could the next game have a title like
batman: arkham war
