Leaps in technology aren't the future of gaming.
The future of gaming is much bigger and much more important.
This is what will happen.... in the future...
1) Game writers will learn how to write stories people care about (it's happened a few times I know, and I've gotten really attached to a story or two, but game writing as a whole is still a joke compared to every other medium).
2) Game critics will learn how to criticize art in the context of the medium, the genre, and art history, instead of only caring about bloom and textures and trophies and writing disposable reviews that everybody laughs at a week or a month later (like claiming GTA4 has Oscar-worthy dialogue).
3) Eventually there will actually be a really big indie breakthrough that will shake up the industry so indie games get much more attention than they do today (like how Paranormal Activity cost one guy $10,000 to make and made over $100,000,000).
I think those are the big 3 changes that will push gaming forward. Tech jumps just make it more expensive so fewer consumers can afford gaming, and fewer companies can afford to make games.
