To be fair, they were using modded versions of Metroid Prime 2 at E3 last year, so they may not have properly started for a little while afterwards.
Also, who knows how much time is needed to really get a great game - Zelda is always delayed for years, yet the quality of the games are better for it.
Likewise, at least they don't overwork their employees. Which company was it that that happened to. Was it EA or Ubisoft or seomthing?
