Wouldn't the sounds have to be installed directly to the sound processor on the Xbox for that to work, or do the sounds go through the audio on the display? Sounds like a good idea if they could get it to work.
I would like to see it return. Also, the ability to dual wield the energy sword (if it returns) would open up some interesting possibilities for assassination animations.
Gamestop.com had the 20gig refurb (origanal 360) with controller for 99.99. Don't know if they are still available. Bought one for the kids, works fine, no issues. Hope this helps.
