To me immersion is better when you can actually do in games what you would do in real life. If you had a squad to command I believe you would tell them to switch weapons or point them what to do. In games people just want everything to perform fast without the slightest body involvement or being afraid to be outclassed by the cpu.
I welcome the voice command for ME3 and hope they'll allow me to use biotics with Kinect. How more immersive is using a controller to talk than actually talking? I think people will feel closer to characters if they can talk to them instead of just pressing buttons. The more I think about it, the more I want to be able to interact physically with games... pressing buttons is becoming last gen.
