Re: i wonder . . .
Don't apologize, it's an interesting question at the very least. Some people spend a lot of time speculating, planning, and buying the "next great collectible."
First of all, remember that folks collect just about anything and enjoy being mini-experts in a particular area. If you like First Act guitars, begin a collection. But don't do it because you think they're going to be worth a ton of dough one day. I doubt that.
New things that are high-quality and scare or rare have a good shot at becoming collectible. In the Ibanez world, DNAs and other JEMs are probably the best bet.
