Syaoran's right eye: They do say he's blind in the right eye in the anime, but not in episode 1-21.

26 eps: I read a post over at bleachforums stating that Tsubasa Chronicle is going to go for 26 eps, take a break (half year?), do season 2 later, have another break, and finish with season 3 a bit after that. So essentially it'd be 70-some episodes with breaks instead of fillers.
