New Batman Arkham City sequel coming soon?

[CM30]

Warner Bros has registered a whole bunch of domain names that seem to point to a sequel to this game, such as the following:

arkhamuniverse.com

batmanarkahmuniverse.com

batmanarkhambegins.com

batmanarkhamlegends.com

batmanarkhamknight.com

dcarkhamverse.com

It's hard to tell whether any of these tie into a genuine new game in development, but they all seem like possible titles for a Batman Arkham City sequel, don't they? And from what I hear, there's a still a lot of questions unanswered in the last two games, perhaps a third game will end the series as a trilogy?

The next game is Arkham World. It is mentioned in dialogue if you listen to the the inmates instead of clobbering them. "First it was Arkham Asylum, then Arkham City. What's next; the massively huge and expansive Arkham World?" "Nah, they'd never do that" "Yeah, yer prolly right..."

It is also seen in the award for best game villain. Mark Hamil in his last appearance ever as The Joker pulls the script out that reads ARKHAM WORLD to which he goes "Whoops! Spoilers~~"

To me, the use of Universe sounds like an MMO name.
