As unique as you may think on a company creating a mind-gaming device, another company Emotiv Systems, based in SF, has one of their own devices (called EPOC) to come out in late 2008 (hopefully in time for the Hanukkah season). The New York Times even talked about them in June 2008:

A new headset system picks up electrical activity from the brain, as well as from facial muscles and other spots, and translates it into on-screen commands. This lets players vanquish villains not with a click, but with a thought.

[...]

The system doesn’t just lift boulders. It can also detect some of a player’s facial expressions and emotional responses: smile, frown or wink, for instance, and an avatar on screen can do so, too. Grow bored during a battle, and the system can detect ennui and supply a few dragons, or change the music. The device tracks a total of about 30 responses.

This system looks far more advanced than the Neural Impulse Actuator and far easier to learn to use, I may have to change my mind on buying the other one and wait the extra few months and pay a little more (twice the price), but it comes with a game and a far simpler system to input with the computer.
