It would not be rude but it would serve no purpose. I am well aware of the interest which is only increasing as the new film approaches. There is a partially completed run of a dozen kits, all of which are spoken for. My Day Job, Family and other projects have delayed its completetion, much to the consternation of those waiting. That's why I never take advance payment or deposits and don't set a delivery date. Too many variables.
I can tell you that it is unlikely once the in-process run has been completed, that there will be another one any time soon. There are several other projects I would rather do.
