Here is my two cents worth...
Firstly, the idea of using numerals is outdated. Renault stopped the practice long ago and using past C= model numbers is plagiarism IMHO.
If A-Eon is really intending to move the Amiga platform forward the model numbers (if they insist) should reflect numerals that Commodore would have use if they had continued building the Amiga line such as 5000, 6000, 7000, 8000, 9000 (not like they don't have a choice!)
As for Commodore USA, I never thought I would have any praise for them but at least they called their Amiga the 'mini' instead of plagiarizing past model numbers.
