That's some strong and clear wording. It makes me wonder if the rumors from before were right and Crytek really did have some type of argument with Microsoft over the Ryse IP.
Regardless, I can't really dredge up a lot of sympathy. They thought the Xbox One was going to be the market leader, or close to it, and they hitched their cart to the wrong horse. They took a gamble and missed, there is no use complaining about that now.
Personally, the thought of Ryse on Playstation or PC does nothing for me. I might consider it at $5 on a Steam sale. Maybe.
I think it's time for Crytek to move on.
