The 68060 is pretty good to be fair, but it never ended up being widely used and Motorola definitely saw PPC as the future.

Maybe if these theoretical new 68k Amigas became a huge market hit they could have taken the arch further and it could have remained competitive, but all the other 68k shops had already pretty much given up or moved on already (Apple was already going PPC, Sun went SPARC, NeXT gave up on their 68k hardware, Atari was exiting the computer business entirely, etc) so I don’t know that the market would have been there to support development against the vast amount of competition from both the huge x86 bastion on one hand and the multitude of RISC newcomers on the other.
