It's already been five whole years since the last one, when Arkham Knight released in 2015. Given the massive success of the series so far and the level of polish it generally has, a new entry in the series is a tantalising prospect.
While nothing is confirmed as of yet, the rumour mill is already churning. There are leaks all over the place, outlining everything from the games' cast of heroes and villains, who you'll be playing as, and the fact that there may even be multiplayer involved.
Said leaks also cover how a completely scrapped title starring Damian Wayne has formed the basis for this new series.
Even more excitingly, we may be able to actually play this title in 2020!
Like the World's Greatest Detective, let's delve into all these rumours and leaks, piece them together, and see if we can figure this thing out, shall we?
Please note that there may be some spoilers ahead for the Batman Arkham series.
