Yeah I'm sure he'll be back. First of all, everyone comes back. Second of all, who else but us would hang on his every self-indulgent crypto-pornographic novella? Third of all, he's maintained a separate dossier on every member of the original A-S on his hard drive since the mid-90s. That's not the sort of thing that is given up lightly. Fourthly, his outrage and sudden disappearance were supposedly directed at the influx of new people (all potential members of the audience for his puerile fantasies). Unlikely if you ask me.
I bet this is a stunt. He's heading off to Japan for some R&R, has some shit to do before then and wants to call us all emo fags when he gets back and sees how much ink we've spilled on his account. I do think it was pretty funny though. Definitely came from left field.
