Possible Upcoming Ultimates
In my recent perusal of skins, I noticed we might be due for another Ultimate skin from Riot. There was Pulsefire Ezreal in June 2012, Spirit Guard Udyr in July 2013 and DJ Sona in February 2015. It may come as late as June 2016 but I wouldn't be surprised by another February release.
With Marksmen, Fighter and Support roles accounted, who do you think are the top candidates for the next Ultimate?
My personal picks are:
Sion (Tank) - Simply because this could be why we haven't seen a skin for this guy since his relaunch. I personally regard him as the Ultimate of tanks. A theme with him as the Supreme Emperor of Noxus would not be too far fetched.
Viktor (Mage) - I can easily see a Final Evolution Viktor package.
LeBlanc (Assassin) - Probably not likely to happen, but I can't conceptualize how an Ultimate Talon or Nocturne would turn out. I honestly don't see an Ultimate Assassin skin coming in the near future, but I would pick LeBlanc over the other two. Something like the Elusive Illusive LeBlanc.
In an alternate runeterra, Kassadin has succeeded in eliminating the void, and contrary to what he thought, his job was not over. After slaying Malzahar, he gained his gift of sight. Using this, he saw that his timeline is, in fact, the only one in which the Void was defeated. Kassadin now leaps between parralel universes with the power he gained in defeating the void, dedicating his life to eradicating it from all realities.
"I have expelled this evil from my world, now I must eliminate it from all others"
Assassin pick: 
Mage pick: 
or 
Excuseme but I am the Great Leader of Noxus
for assassin as it would be awesome to see different kinds of Death Lotus.
