Earlier today I was poking around the internet when I found this.
If this is something Nintendo plans to go through with I would expect an announcement at e3. Some of the more interesting bits are the two screens (one landscape and one portrait), The possibility of running WinXP, and a distribution system for movies, songs and magazines. I would write more but I have some school work to do so I will leave you with this.
Sorry if this is old news.
