Watch how MotionPlus matches movement 1:1 between the real golf swing and Tiger's golf swing. The swing itself is still on a track (it doesn't appear, for instance, that you could make Tiger swing the club like a baseball bat). But our guess is that's a choice EA has made to keep the game's learning curve low.
Plus, the game does acknowledge a slight twist of the wrist to draw or fade with "100%" responsiveness, making this EA video the first time we remember any function related to the Wiimote promising "100%" of anything. Now with the control situation sorted, I can finally return to wishing the Wii had the graphical power of the Xbox 360. [Joystiq via CrunchGear]
