With new update thats gonna come out since you can copy games to you hard drive, wont it be possible to ditch discs and download games from marketplace. Also since you can copy games to your hard drive will that take up more memory than just playing it from the disc.

Well apparently you still need the disc in your 360 to play the game but I suppose if they go to download only that won't be necessary. Not sure about your second question though.

Wait what can you explain the update your talking about

If its the new XBL update in the fall can you show me where you read that because i must have missed it

Its on the giantbombcast.

The game disc needs to be IN the drive to play the game (piracy reasons) so no won't be possible sorry....

EDIT: Just saw iNerd's comment and he's right
