In the latest blog post, Sakaguchi said, "I am working hard on a new project. Now we are being rushed into the 'finishing' stage. No matter what, I will make it really good...." And judging by the tiny surfing Sakaguchi analog seen above, it appears that as the work picks up on this project, the Lego complexity drops. He's really busy.
And we still don't know what he's busy on! The last Blue Dragon game came out on October 8, so this is something else entirely. We should find out soon ... since it's almost finished, we guess.
