Legendary Items for Casters?

If you saw this earlier post on legendary items, you may have noticed something odd about them - they're all designed for melee characters. While I sometimes wonder if this isn't a good thing - it means casters do not feel compelled to go through the long and arduous process of obtaining a legendary item - community manager Eyonix has made a post in the official forums suggesting that we will be seeing legendary items for casters at some point in the future. We'd like time-line, please, Eyonix!
