It's a gag-ending. I'll still make as many round 3 pages as I can, I just wanted something that could reasonably fit as an ending in case I can't get around to THE ending I have in mind. Hell, the most likely thing that will happen is that I'll continue the story as a non-canon spectator entry.
You'll notice it's not part of Round 3, it doesn't link to any specific comic pages and it doesn't say "That's ALL Folks". I hate to get anyone's hopes up, but it's not necessarily over yet, and I'm sorry if I was being misleading.
