As someone who owns the original, I could care less if they re-release it. The best part of a re-release would be no longer having to see the thread on the original pop up every so often and having to hear all those who don't have it whine about how they want it soo badly, but it goes for soo much.
J/K I really wouldn't mind it getting re-released, it's such a beautiful piece and it belongs in as many collectors hands as possible.
Having said all of this I'm sure it will be a mini version. They usually release mini versions of their dios and I don't think this one has been released that way, so it's due. We'll see soon enough.
