Wii Will Download Treats While You Sleep

The Wii will have the capability to download special DS demos, and likely other content overnight so when you wake up you'll get a lovely gift in your living room. And this time it won't be from your cat.

"I'll give you a specific example we are planning for. Let's say your Wii is connected to the Internet in a mode that allows activation on a 24-hour basis. This would allow Nintendo to send monthly promotional demos for the DS, during the night, to the Wii consoles in each household. Users would wake up each morning, find the LED lamp on their Wii flashing, and know that Nintendo has sent them something. They would then be able to download the promotional demo from their Wii's to their Nintendo DS's."
