His opinion is that perhaps the game was announced too early as PlatinumGames strives to create huge games that have no equal among existing titles in things like size, scale of multiplayer and more.
However since the announcement was too early, it created pressure, influenced development, and raised the hurdles on the way to the goal. As a result, this created a situation in which both companies were in doubt on whether the game could offer what the fans wanted. Due to that, it was decided to discontinue Scalebound‘s development.
