"Sony barely mentioned pricing with their PlayStation Move motion controller, only noting that the combo pricing with PlayStation Eye and a game will cost less than $100. But by our back-of-the-envelope calculations, the experience is going to be really expensive.
Our previous look was with the Wii MotionPlus, which clocked in at $80 per person to be fully equipped. That was $40 for the Wiimote, $20 for the Nunchuck and another $20 for the MotionPlus dongle. Now, you can get a WiiMote + MotionPlus bundle for $50, bringing the 1 person cost down to $70, factoring in the Nunchuck. For four people, assuming you didn't trash the bundled WiiMote and Nunchuck from your Wii console purchase, the cost would be $230."
