It would surprise me if Miki's injury was fake. Firstly, she really is injury-prone, and shortly before getting injured she announced she is going to work on fixing her lip (and started doing Biellman again in shows even before that). The injury was sudden, it might seem, but it was hardly the first time she started experiencing problems suddenly (GPF, then dislocating her shoulder during the LP at Japanese Nationals).
Secondly, she always seemed lonely and missing her friends while training in America. She contributed a part of her sucess to support from her friends and feeling a part of the Japanese team. Plus, she enjoys skating in shows. I doubt she would give up the chance to do both (meet her friends and skate alongside with them) not only at DOI, but also at the Japanese traning camp which takes place right now.
About the TV ratings - I wish we had ratings that good in my country during Worlds and Olympics!

The ratings might be lower than last year, but I think it was to be expected. The event wasn't as well promoted as last year, the main starts withdrew, and it is not a post-Olympic season. Plus, I have read at few blog entries from people who were not able to watch the show and asked anyone who was able to help to share the Youtube links... I think quite a huge number of people watched the event online or downloaded the recorded shows when they were not able to watch in on TV.
From those people who watched the show and wrote about it I haven't seen anybody who was dissastisfied. Personally I thought the show was better than last year, with much greater variety of music, a lot of really entertaing programs and skaters that improved a lot since last year.
If there's one thing that I feel the Fuji TV could have done better, is cut the Asada sisters fluff shorter (as a part of it was a repeat of footage that was already aired) and show more of actual performances. A lot of people were really impressed with Akiko Suzuki, Yasuharu Nanri and junior boys, and I was horribly dissappointed when I didn't get to see them.
