British Guitar and Bass magazine had a big feature about CITES and they interviewed people from companies like Taylor and Fender. First on topic:
The Fender guy claims they will not stop using rosewood. He tells that they always try to use legal wood, they will certainly look into other directions, wood wise (*), for maybe American or Mexican Standards, but people who buy a vintage reissue want it as vintage reissue as possible. That's it. Quite a short statement.
(*) On the NAMM I saw different companies trying other woods.
In the article Taylor talks about their wood policy, which is quite interesting. They do use strange woods and are very busy with alternatives for rosewood and they're very active in planting new trees. The article also stated it's still easy for players to transport the basses (10kg max.) and there are different ways for sellers. You can buy a certificate quite easy or like a 'subsribtion' if you sell guitars and basses a lot. For one fee you can ship an X amount of instruments. Not that expensive and not that difficult.
The last thing was guitar world is only a very small part of the rosewood 'probem'. It's mainly furniture which is the problem.
