Some of the nominees for the Tezuka award are recognizable to you, the readers of anime news and blogs: yaoi mangaka Fumi Yoshinaga's (mostly-)not-yaoi take on a female run Japan, Ooku, Yoshihiro Tatsumi's A Drifiting Life (Drawn & Quarterly is releasing it in English soon), and Hikaru Nakamura's Saint Onii-san, about Jesus and Buddha as roommates in modern Japan.
The rest you may not be familiar with, but may see them in the future: Akimi Yoshida's Umimachi Diary, Fusako Kuramochi's Eki Kara Gofun, Daisuke Igarashi's Children of the Sea, and Akira Sasou's Maestro.
As for the Seiyuu Awards, we only have a partial list via 2ch so far, but it's the biggies. Before I list them: the Seiyuu Awards grant awards to voice actors without necessarily specifying what role they've won for, so the roles that I'm listing with the seiyuu are a couple of things they've done within the last year.
Best Actor: Hiroshi Kamiya (Sayonara Zetsubou-sensei, Nozomu Itoshiki; Mobile Suit Gundam 00, Tieria Erde)
Best Actress: Rie Kugimiya (Zero no Tsukaima, Louise; Toradora!, Taiga)
Best Supporting Actor: Kazuhiko Inoue (Detective Conan, Inspector Shiratori; Naruto, Kakashi)
Best Supporting Actor: Tomokazu Sugita (Hetalia Axis Powers, Denmark; Hakushaku to Yousei, Raven)
Best Supporting Actress: Aya Endou (Macross Frontier, Sheryl Nome...supporting? Really?)
Best Supporting Actress: Miyuki Sawashiro (Sayonara Zetsubou-sensei, Maria; Kannagi, Tsugumi Aoba)
Best New Actor: Nobuhiko Okamoto (Chrome-Shelled Regios, Layfon Alseif; Asu no Yoichi!, Yoichi)
Best New Actor: Yuuki Kaji (Kuroshitsuji, Finny; Yozakura Quartet, Akina Hiizumi)
Best New Actress: Kana Asumi (Shugo Chara!, Ran; Persona ~Trinity Soul~, Megumi)
Best New Actress: Haruka Tomatsu (Kannagi, Nagi; To Love-Ru, Lala)
Singing Award: Megumi Nakajima (Macross Frontier, seiyuu and singer for Ranka Lee)
Personality Award: Jun Fukuyama (Code Geass, Lelouch; Spice and Wolf, Craft Lawrence; xxxHOLiC, Kimihiro Watanuki, etc.)
I hope to god there's something for Marina Inoue in the full list-- I think she was fantastic as Iku in Toshokan Sensou, still is fantastic as Kyouko in Skip Beat!, and she's always been good as Kana in Minamike (even if the animation quality dropped off terribly).
