I agree totally a few months back some parents sued the company that made Grand Theft Auto because it made their nine year-old learn words like 'hore'. In my opinion it's their own damn fault for letting a nine year old play a rated M game.
The ESRB puts those things on game boxes for a reason!
It could be that the sun in the game shots are just for effect and to make the game look cooler (Nintendo's probably trying to make up for Wind Waker's graphics). But I guess we won't really know until the game comes out.
