Nice theories!

The nen runes. I think it's going to play an important role in the upcoming Arcs.

I voted for number 4.

I remember though in the manga that Ging said Gon's nen was "fine" when they met. So I wonder what happened there? Ging felt it but Gon can't use it. Ging couldn't have been mistaken. But it makes sense that his nen is still there, ever growing, but he won't be able to use it anymore because that's what he exchanged for for power. I'll leave it to Togashi (if he ever writes again) but for now I'll go with your number 4 theory.
