I think games will be around will be around for awhile yet but I can see movies going soon because of thing like netflix

Yes there is one difference between games and movies. You don't want to rent games, you wan't to play them and keep them for later. Movies on the other hand, you see them once then you're done with it (unless you really love the movie)

For now games will still becoming out on disc, but in the future I wouldn't be surprised to see Digital Download overtake disc use. For games I'd rather see Digital download, but for movies I'd stay with discs.
