Quantum Break joined the delayed games team today as Microsoft announced that the game won't be available for the Xbox One until some time in 2015. This shouldn't be too much of a surprise as Remedy Games has had issues in the past getting games out on time (though I don't recall them saying the game was set to come out in 2014 officially).
The announcement states that game will have a major coming out at Gamescom this August and provided this teaser to show off some of the time bending action from the game. This means we probably won't see a lot of the game at E3 next month.
