There's an entry for it on the anime's official site (the podcast's site has a write-up/summary of it here). Ito and Fukazawa are the other two directors attached to this, and given that there are only three screenwriters listed as well, we're most likely looking at another three-part filler arc instead of something longer, unfortunately. On the plus side though, those three directors are the show's better ones and they apparently consulted with Oda on the story, so there's hope yet that the quality won't take a dive like the others. We'll see how things shake out for sure when the upcoming titles and staff listings leak in another day or two.
More pertinent to this thread, Midori Matsuda teamed up with Hisada for the character design work. She partnered with him on her animation director debut as well.
