During its financial report, CD Projekt RED unveiled the main reasons behind The Witcher 3’s delay. According to the company, the development team is currently further optimizing REDengine3 and is still working on improving the quality of graphic assets, animations, effects and sounds.
The good news is that the main storyline is complete, and the game can already be played in full (in its current build). Although CD Projekt RED is adding more side-quests, the world of the game is completed, meaning that locations are finished and all important gameplay mechanics are already implemented.
Moreover, the team is currently recording voice overs for each language version of the game, although dialogue lines are already closed and implemented.
It’s pretty obvious that CD Projekt RED is polishing its title, and that’s one of the reasons why the game got slightly delayed. Furthermore, the team claimed that one of the reasons the game releases in 2015 is because there will be less competition in 2015.
In addition, CD Projekt RED claimed that this delay will give it time for an improved marketing campaign that will target aware gamers and not random gift-buyers. Also, CD Projekt RED wants to offer the game to more customers and believes that by 2015, there will be more players gaming on next-gen consoles (as opposed to current-gen consoles).
