Nyko has just announced the details of the Wand's release, revealing that it will be released on its own in April for $34.99, and in two bundles in June: the "Core Pak" and the "Action Pak."
The $49.99 Action Pak contains one Wand and one Pistol Grip attachment, which has its own Trans-Port connector on the bottom for connection of additional Nyko accessories. It also features a hilarious orange cap, so people don't think the Wiimote is a real gun. The Core Pak includes a "Wired Kama with Rumble," a version of the Nunchuk with separate rumble motors. It will also be available for $49.99.
Between the slightly reduced price and the improved functionality, we're starting to think about going all-Nyko with our Wii controllers. That seems ... wrong, somehow.
