A small update on Alan Wake was posted on the game's official forums by Remedy.
The key part of the post says "Sure, we've been in development for a long time and if everything had gone perfectly smoothly there probably would be a game out for you guys to play already. But designing a completely new game can be hard, and sometimes you need to take a detour to find the best route forward."
A detour? Hmmm. It could be they went back to the drawing board with the designs or engine, or simply changed up how the game was going to play out... regardless, it's good to know that Alan Wake is still on the way.
