There's one more disruption we might be able to see beginning this generation, the Wii could disrupt TV with internet TV.
Also, the real barrier to WiiWare etc. is the internet itself. A hell of alot of people either don't have a reasonable connection, or don't have the technology skills to connect the Wii up in the first place. The lack of a hard drive is only a problem for people who are already beyond those larger barriers, and have filled their Wii with some games/channels already.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
