Ok, you asked but don't blame me if we're still here by Christmas 2012. :p Anyway, let's start.
FINDER SERIES only if Ayano Yamane does character design;
WILD ADAPTER manga by Kazuya Minekura - "Araiso Executive Committee" sucks if compared to this, why did they
pick that instead of W.A.?!?;
SHINSHI DOUMEI CROSS - they did Full Moo wo Sagashite, why not Shinshi? It's even better than Full Moon!;
MERUPURI manga by Matsuri "Vampire Knight" Hino;
HOT GIMMICK manga by Miki Aihara;
VASSALORD by Nanae "Peacemaker Kurogane" Chrono;
KAKAN No MADONNA by Chihou Saitou;
NEW YORK NEW YORK by Marimo Ragawa - shounen-ai series;
CANTARELLA by Yuu Higuri;
MAYME ANGEL - old series by Yumiko "Candy Candy" Igarashi...
...these are just the first ten positions in my list who more or less contains three or four dozens of manga series I'd like to see an anime of, but it's Christmas and I feel nice enough to avoid posting all of them. n.n
