New Assassin Champ?

Riot said there would be a champion released before the Taric rework is revealed, so what role are they going to fill? Since the mage update is coming along as well as the Taric rework (who is a tank/sup) I think it is going to be an assassin. Our last traditional assassin (not including marksmen or mage assassins) was Yasuo (and even that is a stretch) and so I think the next champ will fill that role, and going with the schedule of new champion releases, we should get a teaser within the next month. So fingers crossed.
