Crafting supplies: will there be a Martini Glass crunch?

I've been thinking about this too, since there are more options to upgrade the crafting level now. I think I'm gonna hold off on crafting for at least all of Act 2. If I stock up on all 3 crafting materials, I'll have a better idea of which ones are more rare or abundant by the end.

The crafting upgrade levels just bug me, its soooo much crafting material to upgrade. I'm sure I'll be able to craft most of the items, but I want as many Exotic Trees and Fikus plants as possible, new greenery is hard to come by.
