Nintendo’s Shinya Takahashi has provided a status update on Metroid Prime 4 today, revealing that “development progress has not reached the standards we seek in a sequel to the Metroid Prime series.” He then stated that  “the current development status of the game is very challenged, and we had to make a difficult decision as a development team.”

Nintendo is now changing the development structure by having the development shifted to Retro Studios. Development will also be restarted. The result is that “the completion of the game will be delayed from our initial internal plan.”
