With all this talk of shiny customisable buttons on touch screens lets not forget reality. Remember that the 3DS, DS and Wii U had both physical face buttons AND a touch screen. This move as shiny as it may look is effectively them removing a feature for little actual gain. If they're going for haptic feedback and multi-touch that's fine but they shouldn't remove the face buttons in the process.
Also remember that buttons are very, very cheap. For comparison a high end mechanical keyboard at retail is ~$1/key. If they were to use those kind of switches in a controller? The face buttons and d-Pad would at most add $10 or so to the total cost. But controllers don't use mechanical switches, they use membrane switches. Keys that are at least 1/10th of the cost. We're talking $1 for them to include buttons.....
