I'm not sure I would call perfect dark something new. They obviously didn't intend to cancel it when they first started but what they did do on purpose is show things way too early with CGI trailers to build fake hype for xbox. In the case of Everwild they didn't even have a game concept ffs. That was completely intentional.Thats a concern. But I doubt they do it on purpose.
They do have some clear cut disasters like Perfect Dark situation. Its kinda unreal.
But at the same time, am not unhappy they have to cancel some of their games. It means they tried new stuff that didn't work out. Making something samey again wouldn't have that risk.
