"Legendary Edition" - box is a replica of Master Chief's helmet, includes 4-disc set:
  • Disc one: game
  • Disc two: documentaries and developer commentary
  • Disc three: spin-off material (Red vs. Blue, Spark of Life, etc.)
  • Disc four: all cut scenes from Halo 1-3 in HD
  • Bonus: sneak peek of Halo movie will be included on one of the discs (maybe)
That sounds amazing, well, until I see the price tag that is. Somehow I'm doubting it will be only $10 more.
