if you look at the lego mindstorms website, you'll see a video showing the new "mindstorms nxt" system. it has a new microprocessor, and new sensors (specifically ultrasonic distance and sound sensors). it departs from standard lego techniques and uses completely studless designs, which you might or might not like (i don't).
the colors are now white, grey and orange and everything has smooth curves, looking less and less like lego.



i've also opened a forum discussion thread for the nxt systems, if you want, participate right here.
