User blog comment:Emptylord/Leaked Champion: Vel'Koz/@comment-5161725-20140201231440/@comment-3974211-20140202055721

Lucian wasn't the first champion released after his artwork was leaked. It's entirely possible that Vel'Koz isn't next. However, I reckon he will be. It's been almost two months and Riot said they were working on something big. I reckon we're gonna get a new game mode/map (there was a poll over a year ago that wanted a PVE/survival game mode against waves of minions) as part of a massive Void patch that will introduce Vel'Koz, the Emissary of the Void (not his title, but his role in the lore).

P.S. +1 what Vhaegor said. Riot said a support would be released early into 2014 - not that a support would be the first champion in 2014. I'm hopeful for a void support, if I'm honest. We're probably going to get back-to-back void monsters for a while - Kog'Maw's dad, Kassadin's daughter, Vel'Koz, etc.
