In a recent interview he talked about wanting to do a card battle manga after HxH. It was pretty funny for him to say that but I think HxH can finish a lot sooner than people think, at least content wise.Well only togashi for me as well.....but I hope finishes off HxH quickly if he can't keep up. A story without an end is a writer's worst nightmare.
I already regret having started the manga. Should have stuck to the anime.
