Heya...
I think you could do a fair bit of, "under the bonnet", work on a mac.
I don't have a mac but I installed OS10.4.8 on my AMD X2. I had to do a fair bit of tweaking to get accelerated graphics, sound and network to function. I really enjoyed the experiment, and no, I don't own a legit copy, so I got rid of the project after a little while.
Sure does make me want to buy a mac though...
ON TOPIC...
I don't think Amiga Inc will produce anything, I would be surprised if they even bother to produce another announcement.
