'Arkham Knight' by RockSteady Announced!!!

Polygon count is still used. Rocksteady just mentioned that

Characters in Arkham Knight are much more detailed, flexing textures and polygon counts three-to-four times higher than in Arkham City. "One character is as big as the polygon count of Arkham
City - the whole environment," said lead character artist Albert Feliu.

Hi. My name is Brilliant and I am happy to assist you today.

Rocksteady has announced that Batman: Arkham Knight will have numerous DLC and Expansions as part of their post-launch process.

I hope this helps resolve your query.

In addition to the Harley Quinn pre-order bonus revealed at the end of the trailer, it looks like there will be alternative Batmobile skins available as well http://www.arkhamverse.com/news/wp-content/uploads/2014/03/2014-03-0520_24_48-bax3ssw.png
which has been confirmed to be driveable inside an open roam Gotham City...

[quote user="From article"]Rocksteady's first two Batman games, Arkham Asylum and Arkham City, both earned "T for Teen" ratings. When Arkham Knight earned an M (suitable for players 17 and older), Hill said the team was surprised.[/quote]

I was only disappointed at the length of the DLC. I enjoyed every minute that took me back to Arkham City! Just wish it was longer, or it would have allowed Robin to free roam the city. Let's hope Rocksteady announces another Batman title tomorrow at
E3!
