Given the source, I'm inclined to agree that this is probably his third-to-last convention, rather than the last. That said, it is Harlan Ellison; I don't think he would be making these claims if things weren't winding down, and I'll be sad to see him gone.
He's kind of like that asshole friend you acknowledge is an asshole while still enjoying his company. Yeah, he's a raging narcissist who pulled a gun on someone to get out of a bet, and he grabbed another author's mammary gland at a convention, but I don't know, it's Harlan. I mean, he wrote, "Repent, Harlequin, said the Ticktockman". It takes a lot of dickery to eclipse all the great things he's done, and he's hopefully not going to manage that in the time he has left.
