The Conduit does look promising! I can't convince myself to pay for a WWII shooter however, so Medal of Honor will remain a mystery. Any idea how Metroid Prime 3 handled?
MP3 handled aiming particularly well within its 3D-Nintendo-Action-Adventure context. Adding free aim to the lock-on-strafe mechanic allowed the camera to stay centered on the target, yet have the freedom to twitch-aim at "distractions" away from the center; a natural evolution of lock-on. Minus lock-on, normal traversal felt downright soothing, tho traditional twitch-aim wasn't useful at this point since the game isn't designed to ambush you from behind (requiring lightning quick turning). But walking and looking around was neatly done.
I hear Medal of Honor Heroes 2 allows the fine tuning which enables proper twitch-aim results.
People also need to get it out of their heads that fixing the targeting reticule to the center of the screen for Wii shooters is a bad idea. What the player inputs must have an appropriate visual feedback. Fixed reticules on PCs work cuz the camera moves with the mouse by moving in a 1:1 fashion. When the mouse stops, the camera stops. The IR Aiming does not do that, since it's based on Remote deflections away from the imaginary center. At minor angles, the crosshair should twitch around inside its bounding-box just as your hand twitches the Remote around; that's immediate, intuitive feedback, and it feels right. Aiming outside the bounding box to make the camera turn is essentially treating the Remote like an analog stick that's pointing at the TV, but at least the crosshair still leans to coincide with the way the player is tilting the Remote.
Fixing the reticule is outright DUMB because you're now dragging the camera to catch-up with the direction you tilt the Remote. With no bounding-box effect, you've eliminated the semi-free twitch-aim functionality inherent in Wii IR pointing. What the Wii Remote is "aiming" at no longer matters, since the reticule/camera exclusively moves based on your deflection from the center. At this point you've turned the Wii Remote into a GIANT analog stick aimed at the TV (minus the traditional IR aiming ability), and you might as well be using a traditional controller now.
