...Another part of the question: Dave Haynie wrote in Deathbed Vigil that Commodore might have survived with 400,000 US sales - could they have made that many sales without the supply problems?
I would say it was doubtful, but there WAS a chance.
So far as I recall the CD32 sold 100,000 units in the UK in short order. Probably a similar amount in Germany and the rest of Europe.
The US market is, what, six times bigger than the UK? However, the Amiga wasn't the popular games machine in the US that it was in the UK/Europe.
I reckon they'd have matched the UK sales at least, and if they got some momentum and good titles out there, word of mouth could possibly have done the rest.
I maintain though that if CD32 would have been a success, then Commodore may have dropped the Amiga computer and carried on with the game console market.
