GameBoy Advance Goes Wireless

Via The Register, here's the new GameBoy wireless adapter (it's neither 802.11b nor Bluetooth).

All of a sudden, wireless gaming is the new gimmick (the N-Gage does it via Bluetooth, the PlayStation Portable will have 802.11b, and the Zodiac will also be Bluetooth-enabled).

I wonder how long it will be before the 2.4GHz spectrum becomes really saturated (no matter what the power restrictions are).
