No access to Stiq at work, but just reading about it it seems kinda like Eye Toy/PS Eye in the waving your arms around department.

The reason this won't ever beat the Wii is because out the gate they positioned the box as a gamer's toy and this thing doesn't come with the system.

The Milo thing sounds cool, but it kinda sounds like Sony's PS Eye pet thing except not as cute. Neither are gonna kick the Wii off it's throne, so it's a bit of a moot point.
