In my opinion, it's going to be a marksman (or a botlane juggernaut ala Morde), since that's the only remaining role (as in the only role not represented in the teasers). Also, he/she could have some kind of magical-based or enhanced armament as opposed to a technological weapon (like Ezreal's gauntlet).

It's unlikely to be a Shen rework, as he was said to not have a major visual and gameplay overhaul. Taric rework is the next in line, but this seems way too close to Poppy's to be real.
