Hmm, from that post in his blog, it sort of sounded to me like he IS joining X. He doesn't say so, of course, but something about the way he talks makes it sound like that to me.
I'll admit that my first thought when I started reading that was, "Sugizo, don't devote your whole life simply to 'channeling' hide!" But he seems so intent on it and serious about it... so if that's what he wants, then cool. Really enjoyed reading what he said about it. And if he DOES join X... sounds good to me.
