Pushing the release date back may disappoint in the short term but I think it will pay off in spades if they use the additional time to get it right. Too many games these days releasing before they're ready and full of glitches or poorly optimized. So long as they don't land in those pitfalls I think most people will be fine with a delay.
Everyone know is not good for the game but for me better is if CI Games delay Sniper Ghost Warrior 3 than release it with a lot of bugs. I hope it is the last delat this game because I wait for it so much.
