I did it in around 38 hours 100% first playthrough but I'm really fast at Zelda games. Most people take at least 50 hours for 100% first playthrough.
Do yourself a favor and don't pass up on Metroid Prime 3 when you get the chance to pick it up. The game's major flaw is it starts out too action oriented, but after that it's great.
Enjoy your new games (and game system)!
