When do you think we'll see a new dark Nintendo game?

There will probably be some dark tones in Fire Emblem IF, and SMTxFE.

A new Metroid could also show dark themes too.

I hope StarFox and Zelda U have darker tones again (Twilight Princess/Majoras Mask were both darker, and Star Fox Assault was rather gloomy at times).

EDIT: Dark themes > Mature themes (hell even early Kirby games had dark themes in them).
