consoles are likely to be almost entirely online next gen. psn already has full blu ray games on it. there are a lot of tricks that devs can use if they know they only have to make it for the hard drive and not a disk.
cartridges work for hand helds because the expectation of hand helds is smaller games. cartidges only make sense (financially) when they are made in small sizes. using small cartidges keeps hand held costs down.
