I'm hoping for bluetooth control of trains, for easy integration with the NXT. I imagine the train motor will be the same (for now) with an add-on bluetooth receiver attached to the studs normally used for attaching light bricks. A bluetooth receiver capable of driving old motors would be good for mindstorms users too.. this would allow one to drive old technic motors from the NXT as well.
I imagine that over time they would phase out the electrical contacts on the wheels (to save money) and possibly make other changes, but I'm hoping they start out by just using the existing motor.
