Yes, I saw it as well. Very amusing, although I was disappointed that the main CT characters didn't speak, even though they were in it at the very end. I also love how Gato kept screwing everything up, and I like the way they portrayed Johnny as well. Question: was it drawn by Akira Toriyama or not? It has that feel and style, but I can't read Japanese credits, so...
BTW, I laughed my ass off as Johnny was flying through the air and reciting that poem. Then the crash...so masterful.
