I wished Clannad wouldn't end. It was spectacular, even though many would say it was just a Kanon rip-off. Which it was, from the first character to the last. But it was also sweet.
Now, their official website hosts a
trailer of Clannad: Tomoyo Edition, a new episode that takes place in some sort of alternate universe, obviously not related to the original series. If you will buy the eighth DVD volume of Clannad, you will also get the chance to watch the full episode. Me, I'll wait for the illegal torrents.
Update: Added the
trailer locally.
