Arse, you can change weapons with the Camera S as always except while Tracking or Running while aiming. If you want to change weapons simply click the R button all the way in to stand still, change with Camera S then unclick, and you're off and running with the new weapon. Otherwise you can run without aiming and change weapons as in Prime. But the method above would let you run and look simultaneously as in Goldeneye or PD.
