Ori and the Blind Forest: Definitive Edition will cost $5 for returning gamers, PC versions delayed.

So, Ori and the Blind Forest: Definitive Edition is launching on March 11th, 2016 after being delayed and I would like to mention it has now been about a year since the game has been out. Current owners of Ori and the Blind Forest can upgrade to the Definitive Edition for $4.99, while all new players can pick up the full game for $19.99, which includes the original Ori.
They have also said the Steam and Windows 10 versions will be delayed. Here is what they had to say:

“To make sure everyone who plays Ori and the Blind Forest: Definitive Edition gets a great experience regardless of platform, we’re taking a bit of extra time with the Windows Store and Steam versions. We will launch the Xbox One version on March 11, and will update you soon on when the other versions will launch. We can’t wait to get the final game in the hands of players and see their reaction!”
