When we rebuilt our manufacturing network we took the chance to redesign the product line to simplify it.We also had to decide the sequence of release giving priority to products that are most popular.Having said this we see an interest for the Due from the resellers and we're working on a solutionIn the meantime the SAM core is still supported and it's getting updated even if we're not selling the hardware

It is industrials which take risk.
But DUE is always manufactured by arduino.org in Italy the only place where they have always been manufactured.
They have the design and presumably the manufacturing data and equipment, so presumably it's relatively easy for them to run off a batch or two now and then. Much easier than for arduino.cc to convince a new manufacturer to make some...
But no, they only show signs of being a pure hardware company, releasing new complex designs (Tian, Arduino Industrial 101, Otto, and now Primo (triple-core!))
