Unfortunately, it does not appear the game will be headed to the Microsoft platform any time soon. Speaking with IGN, Xbox head Phil Spencer explained this is due to business and platform exclusivity.
"It's business," he said, adding he couldn't speak too candidly about the matter. "As I've grow in this role, and I've tried to learn the third-party exclusivity thing - and you see us doing less of it now - [I've found] it's not something I'm a huge fan of."
"Different kind of deals happen, and I know that's part of this busienss, and maybe it'll be my failing in the end," he says, laughing. "But it's not something I specifically embrace with any deal that's out there, whether it's something else. It's just not something I can explicitly talk to."
