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 Supporting Actress: Miyuki Sawashiro (Sayonara Zetsubou-sensei, Maria; Kannagi, Tsugumi Aoba)
Best New Actor: Yuuki Kaji (Kuroshitsuji, Finny; Yozakura Quartet, Akina Hiizumi)
Singing Award: Megumi Nakajima (Macross Frontier, seiyuu and singer for Ranka Lee)
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).
