Japanese games magazine Famitsu has slated Super Mario Galaxy for an October release in its latest list of release dates.
Now, this list could just be a projection of expected release dates, but when it's Famitsu you're talking about, there's always the suspicion that, as is so regularly the case, they may know something we don't.
If the game does indeed release in Japan in October, we hope Nintendo's translators have got their speed hats on because we're expecting it over here before Christmas. You promised, Nintendo.
Also in the list, courtesy of Kotaku, is Wii Health Pack, which it has down for July. No sign of Metroid Prime 3, though. Hmm...
