I think it's safe to say it will arrive in the next generation x5. With the addition of the new touch controller. It's doubtful though that this new system will be made available in the current x5, but you never though.

As noted in the video, the screen resolution has not changed but the CIC hardware has being changed significantly with faster processor and the nvidia graphics processor.

This is still a incremental update to idrive. A newer true next gen system is suppose to arrive in MY. 2014.
