According to this site, FaOI will be held on the 6th and 7th of July which, I think increases the chances of Yuzu's participation in DOI due to the proximity of the event dates of both shows. I was under the impression FaOI would be held somewhere in September, probably they're moving forward the dates so as to not interfere with the athletes' preparation for the Olympics season. I think we should also be keeping an eye out for PIW in Tokyo, held from 12th to 15th of July. If he were to participate in all the shows starting from DOI (late June) until THE ICE (late July), there's a possibility that he'd stay in Japan for one whole month.
FaOI cast: Shizuka Arakawa, Yuzuru Hanyu, Miki Ando, Akiko Suzuki, Kanako Murakami, Stephane Lambiel, Brian Joubert, Johnny Weir, Philippe Candeloro, Javier Fernandez.
Pretty much the same as last year's.
