Phantom Hourglass!!!
Yesyesyesyesyes!!!!!
From the screens, this is more than I'd ever hope it would be. I can only imagine the awesome things we'll see in it, not to mention how they'll do the wifi (you know they'll do it).
Now I can't wait for E3 for them to release more info on it...

Watch the video. It's made clear that almost everything is done with the touch screen. They even show the touch screen being used to write notes on the map, as well as to charter a course for your boat. They showed a line being drawn across the screen, and then Link throwing his magic boomerang along the path of the line. I'm also fairly certain from the video that you use the touch screen to move. Oh yes, basically all of the action seems to take place on the bottom screen.
