We cannot guarantee that, since - see above. when we for (made-up) example get a 500 camrea switches now, then we will be able to sell only 450 devices later on, since the switches will not be available anymore. Again this is a made-up example to explain the situation we might face, ideally the amount of devices we can build is unlimted, but don't hope for that, since it may - and probably will - change eventually. We need to secure/source components and the count of components we secured will determine the size of first batch to build. For a possible second batch we again need to reach a certain minimum count of preorders and then start to see if we can find another maybe 300 (or whatever the preorder count) $whatever-all-the-components-needed (camswitches, RAM chips, etc pp). You generally cannot source an additional 10 or 50 of any such component. You buy one "huge" batch and you hope that "huge" batch is just large enough to meet the minimum order quantity of each component, which often is a 1000 or even 2500.
Hope that shed some light on the situation.
