C=USA existence will lead to confusion between machines running the Amiga OS and machines with the Amiga brand. Since C=USA seems to be able to put $30m into advertising, this confusion is likely to be short-lived, as a Linux-in-heavy-disguise' is made to look like an Amiga-like OS.
C=USA success implying more users and customers for Hyperion/etc seems very optimistic and would, I think, require marketing of Power Amigas alongside the x86 games machines. Think about how the A4000 was the nerd machine to the A500 games machine. That's how I see an ideal PowerAmiga/CommodoreAmiga split.
Unfortunately, Mr Nigro seems dismissive of A-Eon and ACube's products and seems to have no wish to try to bring the AmigaOS on board.
