Already done, Microsoft showed it could be done on WP7* ages ago and PSVita can do exactly the same. There may be one or two things that will be different e.g. Vita and WP7 are both more expensive than one of these controllers, atleast they ought to be, so integration wont necessarily happen but they can do it already.
*WP7 does require its update but I think it is being introduced in Mango.
