This is definitely going to be worth the wait.
The developers could have taken the easy road and for example given us Hitman 11, like it's another iPhone revision. Instead, they wanted to take an already glorious game series, and make it 6x better. Think about it, making it twice as good would be hard, but 6x? That's a very bold and ambitious feat, and the sole reason they are doing this is to give us the entertainment of a lifetime. They are doing this for us folks! The hardcore fans! Remember that. These people are working there butts off, and they are putting forth all their work, time, and creativity to accomplish a grand masterpiece, and Rome wasn't built in a day. That's what the Hitman series is all about anyways right? Elegance, creativity, patience? It doesn't matter to me if it comes out next year, because all of us true assassins know...
Quality > Quantity
I would rather wait an extra year for an absolutely superb product, then receive a mediocre product next month. And I think the rest of the assassins out there are with me. We will wait, because we are a patient breed....
waiting for the kill.
