As you've probably seen, Sharp have developed a 3D LCD technology that requires no glasses and can allow the LCD to operate in normal 2D. Products are expected before end of 2003. See http://sharp-world.com/corporate/news/020927.html and http://news.com.com/2100-1040-978499.html for details. Could Apple be working on displays utilising this technology? Converting apps to support the new tech is apparently pretty straightforward, and Apple obviously have the advantage of controlling software and hardware. Imagine being able to look at your 3D models properly and playing 3D games. Also I'm sure someone will have another go at a 3D GUI, whether it will be any good is a different matter.
