Gosey of SK-Gaming published an interesting interview about 2 days ago, in that interview David "Shawn" K, head admin for World of Warcraft at the ESL answered to several questions, in one of them he is telling us Blizzard will be supporting ESL to set up an online tournament.
Does ESL have any plans to host more wow tournaments?
Since the public's response to the Dreamhack tournament was really positive we definitely plan to stick to WoW. One of the big goals that we have is to establish a 'pro'-scene, especially for European teams. The American scene is a lot more evolved right now with their small offline-tournaments on a regular basis, their infamous BG9 and their 'star-players' that actively write blogs and discuss strategies. The European scene is a lot more cluttered right now and only a handful of teams could prove their worth on a more international level. Our first step will be an online tournament on an event realm that Blizzard is providing us with. There is not set date for that yet but it's definitely going to happen quite soon.
