Anime Sping Season 2009

Winter season is coming to an end so its time to take a look what the spring season is offering.
After a first glance and preliminary filtering the following remains(with respective links to their anidb page):
Shangri-La (like the cover image),
K-on (kyoani of the season),
Sengoku Basara (wondering how they change japanese history),
Senjou no Valkyria(heard good things about the game),
Pandora Hearts(shounen series of the season),
Saki(yeah Mahjong Anime~),
Queens Blade(images in the megami creators makes me wonder what it is about),
Hayate no Gotoku 2(Hinagiku~),
Tears to Tiara(enjoyed the game),
Tayutama (ecchi harem serie of the season),
Polyphonica s2(s1 was reasonable).

Ovas:
Denpa Teki Kanojo(biribiri~?),
To love Ru(because I watched the anime),
Koihime Musou(I don't know why...),
Yurumates(like the art),
To Heart 2adplus(Tama-nee~),
Hayate no Gotoku2 OVA (More Hinagiku~),
Spice & Wolf 2(more economy lessons for current recession),
Higurashi Rei(higurashii~).

Still a large amount of titles -.- I guess the amount will drop after some eps or prioritizing.
