So just how much better is the new brick?  Below you can find a table that puts some of the main aspects of the new EV3 brick NeXT to the NXT.  The original table came from the Roberta website, I just translated it from German.  The source of this information is The LEGO Group, according to the original PDF.  Please note that the images below don’t give a true sense of scale.  The two bricks do not differ a whole lot in size.

Some detailed information about the sensors for the EV3 sensors.  Please note that some of these sensors are for the Education market only and do not come standard with the retail set.

EV3 sensor Technical specifications
Touch Sensor Pressed/not pressed
auto-id
Colour Sensor 7 colours and no colour detected (that sort of makes 8)
Sample rate: 1kHz
auto-id
Ultrasound Sensor Can measure distance between 3 and 250 cm.
Distance is return in 0.1 cm resolution but accuracy is about +/- 1 cm
Can be used to detect other active US sensors (listen mode)
Cool LED light around the “eyes” (or should they be called ears?)
auto-id
Gyroscope Can be used to either keep track of your current heading as well
Accuracy in angle mode is +/- 3 degrees per 90 degrees turned
In gyro mode, it can handle a maximum of 440 degrees per second
Sample rate: 1kHz
auto-id
IR Seeker Can measure distance
Can be used a receiver for an IR Beacon
Can measure direction of the beacon
Can act as a receiver for the IR remote control/beacon
auto-id
IR Beacon/Remote Control Can act like a beacon for homing in on
Can be used to control your robot with buttons; a little like the small Power Functions remote control
