I was wondering about that, now if it is on a console, would this be mapped to the right analog stick then? It would work for fighter mode, however what about other things you might like to map to the right analog in say gerwalk (using a control scheme similar to SDFM for PS2) and Battroid (aiming, similar to most 1st/3rd person shooters).
Also, a cover/action button in batroid mode ala GoW/MGS4.
