Nyko has been creating inventive and functional third-party console gadgets for years, many times improving on the original manufactuer's design with a lower price point. Nyko was at CES 2008 showing off some of their new (and not-so-new) products for gaming enthusiasts.
For one, the wireless Nunchuck is the killer device that Nintendo fans have been salivating over since it was announced: the Wireless Nunchuk Controller Attachment for the Wii.
Do I really need to spell out why this controller accessory is so awesome? There are no restrictive wires, allowing for complete freedom while gaming, and is completely compatible with all games that require the standard Nunchuk. (note that Nyko's Nunchuck has an extra "C" to avoid infringing on Nintendo's trademark).
