I wasnt the only one.
Its distasteful if thats true.
There is no secret Bluepoint project. In that tweet the CM was baiting for attention, maybe teasing Demon's Souls if not announced by then.
They released two games since then, Demon's Souls and later, once they completed it, God of War Ragnarok. Their whole staff appear in the game credits of the games. They don't have more people to work in more projects at the same time.
