yes to rotation sensors / bluetooth / usb / (Score 1)

Let me tell you, I am buying this the minute it comes out. It looks like Lego really went to bat on the NXT, because they've address all of the problems I had with the original kits and then some. The addition of Bluetooth communication is going to revolutionize this kit as a teaching tool for robotics students, allowing for easy communication between robots for some incredible "Social robotics" experiments. And the price is unbelievable too! Most bluetooth kits are $100 alone. Bravo, lego!
