Skarner is still patiently waiting for a new skin.

They gave Darius a new skin.
Then they gave Draven's new skin to Olaf.
Now its Jace's turn.
Zyra next after?

They said they are fixing issues on Norse King Draven,

Didn't Draven come out before Jayce? I'm pretty sure he deserves a skin by now.

Well guys, they said that will be a new PULSEFIRE SKIN in 6 Months...
Draven has no new skin...
Maybe a Pulsefire Draven? lol...

They are going by popularity for the newer champs who only have one skin. That's why Darius received a new skin sooner (he's popular). Draven probably has a smaller player base, but he should receive a skin very soon, if not next.

Judging by this poll, his next skin is probably going to be Bioforge.

I agree, he should've had a skin already. We're just gonna have to wait longer, this happens: Riot picks champions before and after a champion to get another skin, then the person in between gets a better, more thought out skin. Meaning there's a chance this skin will be like Dragon Trainer Lulu, and be worth more.
As a Draven main, I'm still waiting on a new skin for him

Ooh Zyra skin soon hopefully too.
