It's not possible to connect the RealSense kit to the Edison board. However, you can develop projects combining RealSense and Edison just like the one showed in the link you posted.
On the other hand, where did you find that Edison is going to support USB3.0? Could you share the link or document?
The intel staff in China told me they will release new generation edison in the first season this year.
If the edison support usb3.0, it is possible to connect the realsense?
It's not possible either. Applications like RealSense require a lot of processing power. Even though Edison has a good CPU, it cannot be compare with the CPUs used by PCs. It simply wasn't designed for these purposes.
In order to clarify and to avoid any misinterpretation my previous statements and information provided was related to the current Intel Edison platform.
