I think the 68000 was a much better architecture than the 65816.  It was nicer to program and had 32-bit registers which was probably the result of not really being a ISA compatible successor to either the 6800 or 6809.  Perhaps if WDC had built a 32-bit successor to 6502 instead of a 16-bit with some weird performance issues, it would have been more interesting.<p>I do wish something had evolved so we could have something to power the low-end PC market in the original 6052 price range.
