Although I agree that Nintendo could use some more mature themed franchises, I really don't think it would be a good idea to take most of their franchises and move them in that direction ... Zelda is (in essence) a fairy tale, and it seems wrong to have a fairy tale where the hero decides to head to the strip club to pick up some whores before he goes of and graphically kills his enemies.
Where Nintendo has moved in the right direction is getting developers (like Retro, Monolith and Silicone Knights) to produce more mature games (like Metroid Prime, Disaster: Day of Crisis, and Eternal Darkness) for them.
