Update: If you need a hint, several commenters have pointed out posts on XDA Developers by ASUS' Gary Key indicating firmware 220.127.116.11 will arrive "by March 30th" so it shouldn't be a long wait. A possible preview of the features included is also in the thread, culled from a list on the company's Swedish Facebook site for a differently numbered, though also yet to be released update. Check the list after the break or hit the links below to follow the breadcrumbs for yourself.
