From Gamasutra:

Asked if he plans to do any Xbox Live Arcade games, Schafer said, “We talk about making Xbox Live Arcade games all the time. Who doesn’t want to make Xbox Live Arcade games? It’s like when you see a Great Dane taking a giant shit and then you see a poodle taking a little Tootsie Roll shit. The poodle is so cute, but at the end of the day you’re still picking up shit. Seriously though, we’d love to make Xbox Live Arcade games, but we’re really busy now.”

I don’t know if he was just trying to make a joke, but there’s some great sentiment about modern games there.
