Urgot and Shaco might get a relaunch this year. (They are working RIGHT NOW on Urgot and Shaco reworks, said they might combine them with VUs). Warwick is next after Sion who's heaviley in relaunch stages. WW has almost a solid kit and a complete concept art as they wrote in the past few days (Check Surrenderat20.net for more info, in the latest Red Posts). Morde.. Hmm.. He NEEDS a relaunch but I don't think he'll get one this year. Yet, they are completing some important long-awaited relaunches this year. I think that they are working on Poppy too.. They said some time ago that they REALLY WANT to relaunch her, thematically (to make her more yordle-like) and gameplay-wise.. Cause you know- Poppy. No updates on her recently, though.

I assume that Nunu, Ryze and Mundo are next in the line for a VU after the already-previewed Twitch and Karthus VU. Unless Karthus is delayed if they don't got his skins updated yet. I wanna say we will see Sion by July or August. Between all these, I think they might include Tristana or Corki or even Veigar since they wanna to do alot of Yordle VUs as part of their "Great Yordle Unification Pass of 2014" project (yeah that's how they really call it).

UPDATE (Before posted) : I just found something cool IronStylus wrote in the 1/30/2014 (http://forums.na.leagueoflegends.com/board/showthread.php?p=44817047) :

"Karthus is in the pre-production concept phase.

No ballpark date whatsoever though.Nothing on Kassadin, but I'd like to put him into pre-production soon."

Since we already saw an animated new model of Karthus at Pax (https://www.youtube.com/watch?v=xW9ZvY2imAk&list=UU0NwzCHb8Fg89eTB5eYX17Q), Kassadin might be in pre-production phase by now. :D
