Any news/teaser on the next champion?

Apparently it is going to be a male champion. There was a tweet from a Riot developer saying that he's excited to be working on the next champion and that he thinks the community will "really enjoy him".

Really wish it was Ao Shin the dope Dragon lol :p

Or I hope it's Ao'shin

Rito pls

We don't have enough marksmen

I live in hope of a male fire archer, the opposite force to Ashe

a mix of nature + =?

I thought we had a hint about role, but I can't remember anything more specific than that. :\ Maybe I'm only remembering when they said Braum was support.
