I'll watch at least the first 2-3 eps of the following:
Sketchbook: full color's
ef - a tale of memories.
Shion no Ou
I expect to drop half of these after a couple of weeks though. Same thing happened last season.
Genshiken is a must though, as is Juushin Enbu probably. Arakawa ftw.
Clannad, Shana 2, ef-a tale of memories-, Gundam 00, Blue Drop, Night Wizard, Shion no Ou etc. etc.
I'm going to watch everything this season, except the second seasons I haven't watched the first one of..
But Shion no Ou is probably the only one I've been waiting for.
From Wikipedia: Clannad was released for all-ages; this led to a certain amount of disappointment among fans of Key's adult works. Partly in reaction to the disappointment, an adult sequel-of-sorts, Tomoyo After: It's a Wonderful Life, was released on November 25, 2005.
[Fanboy rant] Why is Clannad NOT airing in wide screen!?!?!? The animation is subpar compared to Kanon's. Also, the realistic physics that Kanon and Air had is gone, going back to standard anime physics. I also counted about 5 George Lucas transitions. Even though it's still the same director though, it doesn't look like a Kyo Ani work that much... Saving the budget for Haruhi 2??? Meh... [/Fanboy rant]
