Batman Arkham Asylum 2: What do we want?

GB writes:"If you are a die-hard Batman fan or have become one after playing Batman Arkham Asylum, by now you would have already watched the debut trailer of Batman Arkham Asylum 2. If you would have had a look at the trailer, it seems Joker has shifted his playground out of the Asylum now. It would be interesting to see Batman taking down Joker Thugs in the Gotham city with a larger environment available for stealth action, also different landscapes which could come handy within the Gotham city to stage battles between Batman and his arch enemies."
