I don't know if I'm going to buy any of those that's too early to sat..but I must say they do the exact thing I think can be done with Commodore-Amiga names today.
Can we forget already that a startup could pick up from where the old Commodore where and produce new unique hardware ? That's impossible the world has changed too much. If you want to get anywhere without pumping in insane amount of money you got to use off shelf hardware. And off shelf hardware might even last longer than home brew hardware because it's tested more. Also what's under the hood is not of importance to me. Price and how the computer behaves is more important.
The big question mark for me is "What is WB 5 ?" It might be good, it might not. The ideal situation would be of course OS4 or MOS or AROS being sold with these machines. That's not realistic to happen so C=USA got to do something on their own. This is where I'm very sceptic but I don't have a need to flame them already. I want to see it first. If they are financially strong they could always hire good coders to make WB5 a nice distro or whatever you want to call it.
The PC64 is a different beast. That I believe can sell. And I think this is the project C=USA is really about today. Much hangs on how well this goes out to the retro people. Many here say they could just grab a C64 and do it themselves. I have one in my closet but I would never have the heart to break it apart for something like that. Not even if it were a broken one off ebay. If you don't understand why PC64 could sell then maybe the VIC or C64 wasn't your first computer. It's all about nostalgy here.
