RIOT PLEASE, you have given most of these champions with so MANY skins, NEW skins (
) but what about champs like 
{{champion:427}
and last but not least 
. Please riot, I'm not trying to give you advice on how to run you're business but I'm sure people would buy skins way more for the champs that barely have any if I'm being honest. GLHF!!!

Kayn is still fairly new, he doesn't really need a new skin that urgent right now. And if I had to guess, then I would say we have to wait quite some time for a new skin for him.
Keep in mind that creating a new skin for Kayn basically means the same workload like 3 new skins for other champions, since they have to create the models for Kayn, his Shadow Assassin form, and his Darkin form.
These are quite a bit older than Kayn and need a skin more...
cough cough
The worst part is how well he would lend himself to so many skin concepts
