ICv2 reports early-- sans source citation --that Toei is going to be offering up "200 refurbished episodes" of Sailor Moon at the event, as well as Akira Toriyama's 243-episode series Dr. Slump.
I was able to confirm the information at WorldScreen.com, which posted an interview with Toei's Chief Manager of the International Department, Kenji Ebato in late March. In it he declares his "top properties for MIPTV" to be Sailor Moon, Dr. Slump-Arale (I'm not sure if this means both Dr. Slump AND Dr. Slump & Arale, or just the latter), the One Piece Strong World movie, Marie & Gali, and Master Hamsters.
Yu-Gi-Oh or Digimon).
Interesting stuff all around. Of course, what Toei's "shopping" doesn't necessarily indicate what will actually get bought, but I know there are plenty of people who'd like to get a chance at seeing Sailor Moon Sailor Stars.
