We have always had more than 1 disc for some games since Ps1. Disc changing is no big deal.
On the future front disc of any type, be it Blu ray or any other is extremely old tech now. Sd cards, Flash drives and the like are all limitless in space and are far more durable. Also there is way less load times as transfer rates are far better.
I would hope disc is not for the next generation as 30 gb Sd cards could easily be used in 3 years, or even small flash drives. This is hopefully where gaming will go.
I know Toshiba are looking at putting SD cards to the film industry for Hd films instead of Dics, as you could put it straight into the side of your HDTV(no need for a player) and watch the film that way. You would have smaller boxes to and unlimited space.
