CAN (controller area network) or FlexRay systems?

Brief Introduction:
Controller area networks (CAN) were introduced in 1991 to allow microcontrollers in the engine control unit (ECU), anti-lock braking system (ABS), automatic transmission, etc. to communicate with each other and have essentially been used in almost every car made since 1996. Looking towards the future, new applications such as X-by-Wire require much faster and redundant network connections which CAN will not be able to support due to its low bit rate. To address this problem companies such as BMW, BOSCH, and GM are developing a multiplexed network called FlexRay to handle the needs of the next generation automotive data networking demands.

My discussion question is "How long will CAN be supported after FlexRay (assuming it will become the automotive industry standard networking system) replaces it?"

Another way to ask this question is "How many of you will continue to buy, support, repair, etc. CAN related technologies? If so, why?"


Also if you could include your level of involvement with CAN or FlexRay systems such as "Automotive R&D", or "Automotive Repair Services" with your answer will be appreciated.


Thank you.
