Don't get me wrong, Trevor and Hyperion have done the right thing: Multi-core support in a big-endian desktop OS. I wouldn't build an Amiga on x86. Just because Apple did, we don't need to follow.
"serious money" would fund a team of 15 for at least 2.5 years - depending on education of the team members, this would be between 2.5 and 3 million EUR plus taxes, insurances and stuff. From a German perspective, we're probably talking 4 million EUR cash. That would fund development and production of maybe 20 demonstration units. Depending on the success of these 2.5 years, a second funding round would have to be done for advertising and mass-production.
