So they think the 360 will "own" Holiday 2009... Because of a multiplat, and some glorified DLC?

Show me how much DLC is at AAA status on Metacritic. It's absolutely hilarious how some people try to write it off, but we all know if the PS3 had exclusive DLC for GTA, it would be treated as the second coming of Christ.  But hey, it's not like anybody made a big deal about the Joker challenge rooms in Batman: AA now is it? *rolls eyes*

Were the Joker challenge rooms released seperately at retail?
