They are still working on a decision. They would love to deliver the game to as many people as possible, but they aren't sure they have time to finish it before it's just too late. Plus they are a little reluctant to support Mouse and Keyboard, since they prefer controllers and have designed the game with controllers in mind, thus PC being the last platform to get worked on. If it turns out they were able to make the time for PC development, they will announce it. In short, we don't know yet.

They have not confirmed a pc version.
