According to the Microsoft Xbox website and press site, a new Red Xbox controller is on it’s way September 30th. This limited edition controller features a red body with black highlights. 
The controller will retail for $65, packaged with a charger and matching red rechargable battery.
Another, green themed controller is also pictured on the Xbox press site. This controller comes in the same package (rechargable battery + charger = $5 savings from being purchased separately), although has the standard gray highlights. This green version has not been publicly announced, but is assumed to launch the same time as it’s red counterpart.
