RobbieZ first thing that came into my mind is "who cares".
The biggest thing for me would be - can I travel internationally with my instrument? Answer so far, seems to be yes.
It's only really seemingly to affect the manufacturers, which will means we'll see more alternatives. But guitarists seem to be rather traditional....
Fender's got Pau Ferro, Gibson burnt/baked maple lined up as a alternatives. I've seen fingerboards of african blackwood, purpleheart and ebanol. Graeme Hayward has got all sorts of interesting chunks of lumber waiting experimentation.
I've asked before - Why don't we have more composite materials? I really liked the ebonol fretboard on my old Cort Curbow. I'm guessing that price/performance doesn't quite line up - yet - wood is light, aesthetically pleasing and durable...and tradition.
Perhaps wood laminates will be explored more. I've a 60's mij acoustic nylon that is tougher than boots and sounds surprisingly good despite being 100% made out of various wood laminates.
