CertainlyT's Next Champion is a Dinosaur

Now that I've caught your attention... I hope to start another discussion for theories on the next League champion. I know, I know, it feels rather early to be thinking about that already, but we already have three hints:

My next champ will be storming Summoner's Rift directly after our next addition to the League. GypsyLord's second champ stole the spot ahead of me.

and

Yeah I suppose exact dates are still up in the air.

and

Don't listen to CertainlyT, he's known to blow things out of proportion lately.

Since Jinx isn't Janna in disguise, I'm assuming this relates to his champion. But we already have Janna... and Kennen/Ao Shin for lightning... so how could it be different?

An interesting thought that popped into my mind is a 'sandstorm' champion. Given the Xerath rework, the Sivir VU placing her in Shurima, and what looks like new lore for Cassiopeia, Xerath, Nasus, and Reneketon, I believe that the next champion will be from or related to Shurima. Riot probably wanted to do a Shurima event before Halloween, but Lucian's two month delay caused it to be pushed back to now.

A sandstorm champion that allies themselves with Sivir and Nasus would even out the champion page's friends and rivals page, where Xerath, Cassiopeia, and Renekton seem to be against them.

Another thought is that we're due for a support or a mage. We've had three ADCs, two fighters, and only one mage and one support this year, so we're about due for another one of those.

Also, Shurima teasers where? Riot please, I loved the other teaser-stories, I missed those from our past two champions.

But what are your guys thoughts? Do you think CertainlyT's champion is from Shurima? A 'good' guy? A support mage? A dinosaur?
