In single player? Why not. Multiplayer? Only if mouse and KB come with the console.

What they should do is remove autoaim or aim assist or whatever it's called, no matter what. 

Hell yes.

Keyboard and Mouse is by far my favourite controller.

Precise, Customiseable.

everyone on a console should use a pad, i actually prefer it.

If you have some people with a keyboard and mouse and some with analog, then it's not fair.

When everyone has a pad, it's fair.

So if you want to use keyboard and mouse, you should buy the game if its on the PC.

Call of Duty, Bioshock, Gears of War etc.

So many of the FPS games are also available on the PC that I doubt there will ever be much support for giving consoles PC like controls, same for RTS.

Likewise I detest dual analog control, for anything. Actually my preferred scheme for FPS is the scheme used for Link crossbow especially using the Zapper.
