I have joined this discussion late so have to ask..Am I missing something?
Surely controls will be using duel analogs like a 360 game with shoulder buttons for shooting jumping and dpad for change weapon etc
People are just brainstorming really, there's a touchscreen there to be used so it's only natural that the possibilities are explored.
If it's done right, the controls will be fully mappable. I'll be keen to try it console style as you mentioned, and I'll also be interested to see how the touchscreen is used (if at all). But I'd really like to play with WASD+mouse whenever possible.
Options for the win.
