The first is an updated version of PDP's "Paintbrush Chuk" accessory, designed to mimic Mickey's paintbrush. The new version has the Epic Mickey 2 logo and a glowing blue paint blob at the end of the brush. The second, and inexplicably more desirable of the two, is a Nunchuk based on Oswald's remote device, silver and boxy. It's like a literal "Wii Remote" (except, of course, it's a Nunchuk attached to an existing Wii Remote).
Being that these were both prototypes, and the game hadn't even technically been officially announced yet, there weren't any details to be had about pricing or availability. We'll keep you updated, because these silly controllers are fun.
