Indeed the next decade will be totally wireless as Wired predicts:

"A new wireless technology with enough bandwidth to carry cable television signals from a wall-mounted outlet to a TV anywhere in the home could be on the market as early as next year, an industry group said Tuesday.

The Multiband OFDM alliance, led by Texas Instruments, the world's top maker of microchips for cell phones, said it would publish standards for the technology in May. The group said it expected products with the technology, known as ultra wideband, to ship in 2005."
