Rainbow Six: Siege completely blew me away at Ubisoft's E3 press conference, and the company has been steadily releasing more and more info about the game. Hey, they even confirmed that the game will run at a solid 60fps on all three platforms, so they got that out of the way early.
“It really came from the gameplay side. We felt that the only chance we had to come with something that would be impressive in the online FPS arena was to have 60 frames-per-second and no limits imposed by having single-player. That’s what made us change direction,” said Ubisoft CEO Yves Guillemot in an interview with CVG
Rainbow Six: Siege has a 2015 release.
