There will be zero supply of Engel machines at launch and for a very long time. Apple will purchase the present and "future" supply of the machines. Ie: Engel won't be able to make them fast enough to fulfill orders. This is the same thing that happened when Apple bought up all the CNC devices. Apple's competitors could not get access as Apple had already locked up the future supply.
Apple will get preferential pricing for this reason but it will ensure we have a steady and increasing demand for years to come!
Mark my words. Apple will have a secrecy clause over this until the time they choose to announce a device made from Liquidmetal.
