So, I tend to hold out with purchasing HF&J products until more styles are introduced. Economically, it's probably a better model for type founding because it's a more efficient use of development time in terms of reducing long periods of time without profit. I still get kinda bummed when I buy a "family" only to later find out that a few more kids are on the way. (Ahem, Archer, Gotham, and well every HFJ).
So, based on this speculation....who wants to predict what's next for TUNGSTEN? Right now, 4 styles.
If Tungsten follows suit...
Round 1: 4 italics and possibly a rounded or hairline. (Not sure if rounded would work with structure.)
Round 2: Hopefully an EXPANDED and italic expanded.
Round 3: Drop caps and numerals.
