even if commodore made it to the next chipset level, I think they would have still be in trouble unless they utilise more off the shelf components /cards from other manufacturors using open standards just like what the PC did. ie. Gfx, Sound cards etc,
R&Ding your own custom chips, slows you down increasing the time between new technology releases as they get more complex. Best if you can shift that to 3rd parties to free up your own resources.
