Everyone was disappointed by Watch Dogs’ delay. There was no way that this could’ve been avoided. There was a crazy hype behind such an innovative and beautiful looking game. But Ubisoft had its reasons.
As expected it wasn’t’ a easy decision for Ubisoft and in a recent interview with IGN, Ubisoft North America president Laurent Detoc, he said the decision was ultimately "very intense." He continued to say,
"I think one of the fascinating things about this industry is that you can go from genius to idiot in an extremely short time frame. These are some of those moments, where you’re riding sky high on Watch Dogs or Rayman, and then suddenly you have to break it to the outside world, and sometimes even convince the inside people. Not everybody agrees. You have to say, ‘this is in the best interest of the product, to do this,’ because at the end of the day we’re going to be able to do this extra fine tuning."
He also add that the game "just wasn't ready" and that initially they believed that the game would be go for its November launch as of Gamescom (which was in August). He said that if released then the game might have been called "best-rated game on next-gen," saying Ubisoft is "breaking ground" on certain gameplay assets. However this was still not good enough. He mentioned Grand Theft Auto V as a bar that they wanted to overcome.
Hey I am okay with waiting, but now they just increased the expectation level by that much more. I am sure we will be wowed by the game, but preconceived expectations are tough to match.
