Has there been any mention on shoulder mapping?

[zergslayer69]

for those playing on an android device (phone or tablet) it's fairly inconvenient having the L and R buttons at the furthest possible location from where the other buttons are. Is there a way of moving the shoulder buttons so that they're right above the dpad/action buttons? Or maybe, has the devs mentioned anything about possibly being able to move the location around in future build?
