Halo 3 Details: Mongoose, "Man Cannon"

Xbox 360 Fanboy, and Kotaku, uploaded a little list of what "should" be coming to Halo 3. I'm a huge fan of the "man cannon" and visible second weapons. Though, now I can't be the ass that comes up on you with a pistol and *suprise!* takes your head off with a sword.

• Spiker - a new Brute weapon
  
• Spartan Laser - a laser that tears vehicles apart
  
• Nail Grenade - sticks into walls, sends nails everywhere
  
• Mongoose - the ATV that was cut from Halo 2; seats two, but no weapons; designed for recon
  
• "Man Cannon" - what it sounds like; launches you into the air (think: jump pads from Unreal, Quake Arena)
  
• Right and left bumpers are used to reload the right and left weapons independently
  
• X-button has a "secret" function
  
• Secondary weapon is now visible when not in use (slung over shoulder)
  
• "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)
