Think about it. With the DS's enhanced graphical power over the GBA, not to mention the dual screens, touch screens, and WIFI, it seems like it could done. ED started on the N64, and if Silicon Knights still has any of the old code left, they could port it over or, better yet, create an all new adventure using the abilities of the DS. Imagine some of the puzzles and insanity effects that could be done. FOR EXAMPLE:
Ougia board puzzles, fake battery alarms/power offs, launching picto-chat with creepy messages or even voice recog puzzles, pictures that suddenly appear and dissapear from one screen to another.
There are more but it's late. Please tell me I'm not the only one excited about the possibilites...
