Sure it is on March 30th, but it is never too early to start the annual rumors. I was referred to an article at a website known as Game Focus, where they stated that Ocarina of Time is rumored to be available for the Nintendo Wii. Here is an exact quote from the site.
“Apparently Nintendo is not done with the cool announcements. After announcing The Legend of Zelda: Spirit Tracks last Wednesday at GDC, it seems like the Japanese firm has another huge announcement to make this week.
Late last night, our Japanese contact over at Nintendo sent us word about something really exciting: a Wii remake of the one of the greatest N64 games ever produced: The Legend of Zelda: Ocarina of Time. We were also told that an official announcement would be made around April 5, which is the North American launch of the Nintendo DSi.”
It states we might find out more information on the 5th of April, but the days after April 1st might be a more reasonable date. Seems pretty crazy that we would be hearing this information, just says after being shown a brand new Zelda title in, Spirit Tracks. It seems only time will tell.
