"I even invited your best friend the companion cube. Of course, HE couldn't come because you murdered HIM." - GLaDOS. Proof. But, it's okay, Companion Cube loves everyone, and everyone is gay for Companion Cube.
You don't get points for just Cosby. And calling it "pokegaymenq"? Haven't lameass Pokémon puns been old since... 1998, when the series came to America?
Series creator Keiji Inafune wanted it to end at MMX5... which obviously didn't happen. So don't rate this based on "it'll never happen", because you can't predict the future. Not to say anyone should get their hopes up, but anything is possible.
Why does it matter what has been said NOW? The future is unpredictable. And Bandai Namco holds the cards when it comes to Katamari. They own the rights, and have the final word if a new Katamari is made or not.
Take for example, Capcom's Megaman X series
