The future of video games?

Maybe I am giving away my age, but I remember playing pong on an Atair. I thought it was amazing and could not get enough. Today, the games have advanced to an amazing level. My youngest son has a Wii, a Xbox 360 and other video systems. Things have changed.

What is the future of video games? More mobile gaming? New ways of interacting with the game? How about 'Touchable Holography'? This is too cool.
