50GB isn't that impressive. Remember that they aren't focusing on variety. Lots of that goes to graphics, physics, audio, and well, you get the idea.

You can make a big game and have it be crammed onto a tiny disc (let's say 9GB DVD) like GTA: San Andreas was.

Pretty much what I am saying is that, there will be a lot of game here, but there won't be much variety.

That statement doesn't make sense.

You can make a big game on a tiny disc, by reusing the same audio or textures a lot, and compressing a lot.
Now you have a big disc, you can put more textures, more audio, more content.

So how do you come to the conclusion of less variety? and how is it not that impressive?
