"It seems that there's some bitterness between Hideki Kamiya and Microsoft, this according to a furious statement made by the Platinum Games' designer regarding the Redmond company over on Twitter.
It started with a rude Tweet (later removed, but a user on NeoGAF grabbed it in time), where Kamiya wrote in Japanese (as translated): "Those sh**s at MS... are they f**king with me...?".
It's not yet clear the reason that Kamiya turned on Microsoft, but it might have something to do with Scalebound, the title that Platinum Games is developing exclusively for Xbox One and that the company will show at Gamescom during Microsoft's press conference next month.
At the moment Kamiya hasn't given any other clues as to the issue he has with the platform holder, and we're going to have to wait and see what has provoked his wrath. Maybe we'll find out during Gamescom."
