Just incase you still weren't convinced, MotionPlus and WiiSpeak reconfirmed for The Conduit

“We’re hooking it [MotionPlus] up. We want to support it. Probably for this version of the game there’s not going to be a whole ton of really extensive use of the Wii MotionPlus. For the sequel to the game, we definitely do want to incorporate more melee and things like that. We want to support it.” - High Voltage COO Eric Nofsinger

We have posted a number of articles and press releases in the past that state these facts, but it seems like people either missed those, or just don’t believe the information! There, once again, straight from High Voltage is yet another confirmation of both WiiSpeak and Wii MotionPlus. You can read more of Mr. Nofsinger’s thoughts on MotionPlus right here.
