I think the real problem was the cost of more powerful CPUs (and associated harware) during that period. But this 'problem' turned out to be an asset for Amiga owners, because it meant they didn't...

You say that like it was a bad thing. To us A1200 owners the idea that new Amiga games might target the CD32 only was not a nice thought. OTOH, being able to use the A1200 to develop CD32 titles was...
