I don't speak for the company but if there is an upgrade it will be in the form of a pcb replacement, either the USB, DSP or analog board. If and when it's available, that upgrade will be offered as an add-on to the base model and will probably be in the same format as the other buy buttons -- pick the base model and then pick the add-on from a menu with the associated price.
Implying that future buyers are going to get the upgraded unit at the same price as today is misleading and, IMO, not a nice thing to do.
