I think the other point is we have decades and decades of code at this point written in C, or built on top of C. In some regards 'if it ain't broke don't fix it' holds quite a bit of truth. The embedded world may start to move to doing more things in a higher level language to speed up development in areas that may not need the same level of high performance or real time certainty. Stuff like TI RTOS while still C made getting to a proof of concept much faster.
