Ntkrnl, an insider on NeoGAF, who has been pretty much dropping bombs all day, has revealed that Platinum Games is working on an Xbox One game which is codenamed Project Nagano.
There was a rumour earlier as well from another extremely reliable insider called CBOAT, who also confirmed that Platinum Games was developing a game for Microsoft.
He says that it is scheduled for release in March 2016, which is a long time, but makes sense. Take this as a rumour for now. We will keep you updated as we hear more on this.
