A new Halo means a new Xbox bundle. This time it's a silver "new style" Xbox 360 with Reach decals, two silver-painted wireless controllers, and a standard edition copy of the game for $399.
A little earlier than that (early August) those of you predisposed to buying such things will be able to pick up the controllers and a wireless version of the headset for a hefty price tag. The controllers will set you back a whopping $59.99 and come with an Xbox Live token for an animated Covenant Banshee avatar item (to make you feel better about buying such an expensive controller, presumably) and the wireless headset is $49.99. No freebies with the headset.
Microsoft is claiming that these accessories are both "being produced in limited quantities" and would like you to know that they are available for pre-order now. So, have at it.
