Sony to Compete With Segway?

A recently filed patent application from Sony shows that they are working on a technology that is similar to that in the ubiquitous (and superfluous) Segway Human Transporter.
The patent abstract, titled “Vehicle steerable by movement of center of gravity” describes the invention as follows:
…a vehicle which can travel in the front and back direction and which can turn by right and left wheels rotated when a rider riding on a step-board moves the position of rider’s balance from the center of a vehicle base.
