Disappointing, but not unexpected. As people have already said though, it is best for them to just take their time, especially now that they are working on a massive world which is something they have never really done before. Regardless, I am pretty damn sure CD Projekt Red will deliver a quality product like they have before.
Based off this, I am going to take a wild guess and say Cyberpunk 2077 is most definitely not going to arrive in 2015.
