I'm looking forward to when "fold" is not so equivalent to "premium". I'm interested in a folding phone, but I don't think I've spent a cumulative $2000 on my last 4 phones. I'd have a hard time justifying spending even $1000.

I'm also looking forward to nomenclature settling so the horizontal-folding passport-style folding phones (like this, which I find interesting) can be more clearly distinguished from the vertical-folding flip-phone style folding phones (which don't remotely interest me).
