I'm going to guess January 31st. If anyone guesses the exact day they will receive x1 legendary pat on the back.
September - We need a rune called 'True Optimist'... Winter 2016 in Northern Hemisphere started on Wednesday, December 21 and will end on Monday, March 20, 2017 I say Feb 2nd, Groundhogs day...When will Winter last, who's Shadow will the Groundhog really see? Will it be a Mogas or a Corgis?
I'm gonna be the optimist and say we're gonna at least get a preview by Jan. 5th as a birthday present to me (hint hint @Sokolov @Senshu), with the actual release sometime around the 12th, give or take a day.
Oh when I bring up how long it's going to take I am a troll, but now look at everyone trying to predict the date just like I did weeks ago. FEB.31st at the earliest, most likely they will use half of their staff to try to kickstart another game that is more eye appealing to the average gamer which will postpone that date.
