there is no more money in arduino hardware anymore. its a fact.
business model is hard. the value is the software and libs and user content (MOSTLY user content! its all about the libraries and examples that let us all do rapid prototyping).
I bought some 328 arduino italy boards when I first started, at $30 or so, each. maybe more, I forget. but they were expensive and I stopped buying them once I could do my own boards. and now, even my own boards do not make as much sense; since I can buy a usb nanon 3.0 board for $5. sure, it has crap ftdi fake chips on it (sigh) but newer ones are using non-ftdi chips and so that's good progress.
the size of a nano v3 module is great, its all there and its hard to argue with that kind of easy integration. but no one buys italy or official nano modules. they exist and i'm sure they are better made with real parts, but they cost too much!
I hope they can find a good business model. the arduino guys did a big thing to help the world get into controllers (major game changer; they deserve full credit) but now that chinese clones are out there, the hardware side is 'solved'. sad but true.
arguing over who sells the hardware is a lose/lose game.
