OXCGN discusses the new Limited and Legendary Edition of Halo Reach and limited editions in general:
"The new Legendary Halo Reach Limited Edition Noble One Team Statue will drop on your desks at a cool 5kgs, not including the huge tin box, the huge Diary, Cloth Badge, Security card Artefact bag and other gear.
There are two items available outside the standard edition of course.
