To my understanding, it is embeded system. So, I guess they don't have .Net for it. Personally I don't know the whole story behind it.

I agree with the performance statement. Although if you really start to crunch the performance, C++ is definitly faster. The caveat is, crunching that performance is very challenging and often makes more mistakes on the way. But, some companies do have the resources for that.
