Gamesradar- "Game cancellations are a sad reality of the video game industry. There are so many moving parts - hardware, software, marketing, promotion, publishing - that some titles fall through the cracks, no matter how gargantuan and obligatory they might seem. Sometimes it happens abruptly, while other times the cancellation of a game is never truly revealed until, well, the game just doesn't come out.
That's not to say that there are no signs. Usually it's fairly obvious when a game is getting cut, and there have been a number of major games this generation that appear to be precariously hanging over a bottomless pit, despite the assurance from the developers that everything is fine. We've rounded up the games we have the worst feelings about, and we hope we're wrong about literally all of them."
