Quinn's shown up on the radar in a new way recently.
Surrender @20 posted that they had found mention of 'Quinn' in the PBE files. As it says in the article, this file could be a placeholder for another champ, the name of an upcoming champ, or quite literally -- nothing at all. it was brought up on my thread, but I'll say it here too; I don't know anything about it. Riot didn't ask me about it or contact me about it in any way shape or form.
If it is the name of a new champ -- I'm just glad that they'll finally be filling the empty space where a 'Q' name needs to go. That 'Q' name being Quinn is just a really really great coincidence that I totally approve of.
