One Minute Of Batman: Arkham City

Can you believe it's almost my birthday? it's almost time for the release of Arkham City?
Arkham City is coming out on the 21st of October (My birthday) and any footage of one of the most anticipated sequels of the year (and my most anticipated game of the year) is appreciated. Especially with recent comments from developers about how much bigger and vast the game is. So any trailer or gameplay footage is appreciated, especially when it involves Batman gliding or beating villains in an alleyway. Because it's what I was expecting, and I can't wait.
