Although I do agree that Wii Motion Plus isn't necessary, it is nice to have around, at least maybe as an option. I noticed that Modern Warfare seemed to detect Wiimote movements significantly faster than The Conduit, and I really liked that. I'd be all right with The Conduit 2 not having Wii Motion Plus if it detected movements as quickly as Modern Warfare, but I'd still appreciate having the capabilities of Wii Motion Plus at my disposal.
