I have been reading Kobato and Kimi no Todoke... they're good! I specially like Kobato because it is by Clamp, and their art is sooo gorgeous. I'll look forward to the anime series!!!
The other upcoming animes seem good too...
Why make a winter sonata anime, though??? I think that it's too dramatic for anime...
My watch list for the fall season seems to keep on increasing, lol. However, I always end up dropping something I thought I would have enjoyed to then later pick up a series I originally had no interest in, (such as this season with Canaan), and completely enjoy it.
So, here's my tentative watch list (not including OVAs):
1. Nyah Koi!
2. Kampfer
3. A Certain Scientific Railgun
4. Letter Bee
5. Kobato
6. Kimi Ni Todoke
7. Sasameki Koto
8. Blue Literature
9. Fairy Tail
