>>>So should I be stocking up on the Tri-X and Portra films soon?

No, but you should periodically test some alternatives, just in case.

You B&W guys seem to be set, but there aren't a lot of alternatives in color, and I'm not sure I have the patience to make 120-sized autochromes. It will be depressing when my TLR becomes a prop in a still-life, rather than an active tool.
