I would think eventually the future is going to go more and more towards the artificial surfaces, like ebanol.
I don't know much about it and haven't tried it yet, but I have heard some glowing reviews (a friend tried a Martin guitar with a composite fretboard and raved about it!!)
I know many of us love the look, sound and feel of woods, but with improved technology, and decreasing/more protected natural woods (thus increasing price), I can't help but think that we'll be seeing more & more of these products.
Im sure this will be a lively argument in upcoming years on talkbass and beyond. I like to consider myself open minded, so I'm anxious to try one, to see how far the tech has come to sounding/feeling like the real thing...lucky for us there are still plenty of beautiful basses out there with real wood!
