It sounds like this will be a limited run, of basically some old refrigerated stock of Polaroid materials (paper), with a mix of (new reagents, non Polaroid), home brew, developing chemicals.
From 20X24 Facebook thread:
20x24 Studio This is the original Polacolor ER, purchased from Polaroid and kept in cold storage. New reagent will be mixed from our chemical compounds. It is essentially fresh T809, but we will not call it that. It will be a limited run and will test the waters to see if creating a new color emulsion is viable.54 minutes ago
20x24 Studio As we stated before, we have some assembly logistics to set up, but our intent is to make this happen.
This really doesn't sound like a sustainable "new product."
More, a last gasp of an "attic find."
