AAA was I think going to introduce PCI slots and for the high-end Amiga's potentially move the custom chipset out onto a seperate card.
When you think about it the modern PC is just a big CPU, ram and storage with a bunch of custom chipsets for doing the hard work like graphics and audio etc. Which is what the amiga was albeit the amiga was a single integrated unit.
With the management of Commodore it was probably always doomed regardless of the timeframe.
