Who owned Commodore? The investors. Who killed Commodore? Gould primarily with help from others. How did they kill Commodore? With greed, poor advertising, and stupid marketing decisions that are complex: the C64 should have progressed to a 16-bit version and the Amiga line should have been cleaned up (read Steve Jobs bio on how he turned Apple around from near failure). This is my opinion
Yes, a 65816 based C64 successor. A big missed opportunity, IMHO.
