If no one minds, I have a few questions...
Why was Syaoran so hesitant about reading Sakura's letters? I understand that he has been away from human contact for a long time, but one would think that, if I read into it correctly, he receives letters from Yukito. That's one reason I would really like to see what he replied with. I wonder if he asked if she had possession of the pen.
I also want to see Yukito's reply to Sakura's inquiry. It must have been a shock to her to actually see magic, instead of knowing that it used to in the world, and the off chance possibility of it still existing. It would be insightful to see the Duke of Summers explain.
And what is the exact relevance of the Kinomoto household? It seems important somehow, but we know they hold no magic. Why was it brought up?
