DreamHack has announced the dates for its 2012 tour which expands to a total of five events with the finals event being DreamHack Winter.
As usual, the main events are DreamHack Summer and DreamHack Winter, but they have also included a total of three other events in their Open series. They also claim that the events will feature a new and more improved eSports format for both professionals and amateurs.

More Counter-Strike to come at DreamHack in 2012?
The games list for all of the events is not available yet but will be announced at a later date. Counter-Strike has been the most popular game at the past DreamHack events, so the chances of it being featured in at least the Summer and Winter events are high.
