To give you some examples of 8-bit micros being currently used, apart from HU controller:
1. The venerable old company Zilog still makes a Z80-derived micro, which is the mainstay of most Remote Controllers for TV, HT, DVD etc., apart from the programmable remotes
2. Most of the engine management ECU for low-end cars are based on 8051 derivatives
3. Most digitally controlled elevators in operation today are controlled by 680x-based control systems
4. Most common PMPs are based on a Philips chipset, which has an 8 bit controller internally (not the CODEC)
Most of us get carried away by Moore's Law and Intel's advertising, forgetting the fact that the bulk of micros and processors working in the field (outside of PCs) are in fact the old clunky slow ones like Z80, 8051, 6809, 68K, 99xx, etc. and their derivatives. They outnumber Pentiums et al 10:1!!! Of course they are not sexy or news-worthy, so you wouldn't have heard of them.

Why can an 8 bit micro not decode to 16-bit audio? The stream is 8-bit bytes only, no?!
By your logic, a bus-driver should be 3 times the size of an average M800 or Alto driver!!!
