So far, none of the footage has shown that people have a clue at customizing their controls to achieve good aiming results. All they've shown is it's a FPS where you can run faster than Michael Ford.
Is it me, or does Treyarch's Call of Duty's close-up aim look completely awkward with IR Controls? The gun doesn't appear close enough to your eyes, yet it floats around inside the bounding box without any angular adjustments. Hell, I didn't like how it was implemented in Treyarch's World At War. I prefer something more like Conduit, where the view lens size is generous enough and floats easily without filling the screen with an awkwardly placed gun model (the CoD system is fine for fixed-center FPS views, but not Wii's IR movement), but as an addition it should still show the un-zoomed scenery around with depth-of-field blur, akin to RE4.
