Halo 3 Mythic Map Pack Trailer

Just when I thought I had curbed the Halo 3 addiction, Bungie goes and releases this Mythic Map Pack trailer. The map pack will be hitting tomorrow April 9, and sports 3 brand new maps. I think the most intriguing thing about it is Sandbox, which has 3 different spaces for tons of Forge-ness to take place, which will no doubt lead to lots of community created custom games. And those always rule. So, are any of you guys planning on picking this up?
