I like to choose what animes to watch at a new season by looking at all of them. The would watch the ones I found to be interesting and/or it's art pleases me. In a way I kinda afraid to miss a good series (and yeah I know I could just watch it later

The following ones are the ones I will watch. I may drop some of them but not before at least 3 episodes of each. (I got the start dates from MAL database)
+Basquash! (April 02)
+K-ON! (April 02)
+Queen’s Blade Rurou no Senshi (April 02)
+Pandora Hearts (April 02)
+Phantom Requiem for the Phantom (April 02)
+Hayate no Gotoku 2 (April 03)
+Shinkyoku Soukai Polyphonica Crimson S (April 04) (Need to watch previous season first)
+Senjou no Valkyria - Valkyria Chronicles (April 04)
+Tayutama -Kiss on my Deity- (April 05)
+Saki (April 05)
+Dragonball Kai (April 05)
+Shangri-La (April 05)
+Fullmetal Alchemist (April 05)
+Tears to Tiara (April 05)
+07-Ghost (April 06)
+Asura Cryin’ (April 06)
+Ristorante Paradiso (April 08)
+Eden of the East (April 09)
+Hatsukoi Gentei (April 11)
+Fight Ippatsu! Juuden-chan (May)
The ones I'm hoping for the most are Hayate no Gotoku 2 (need my Nagi, Hayate, Hina and Maria fix), Tears to Tiara (playing the VN and it's quite good) and K-ON! (KyoAni ftw). I'm quite interested in FMA and DG Kai too(they will be much easier to watch one episode a week). Let's see how those two will go.
Next are ones in which I was interested enough that I may watch them if I have enought free time (that's not probable though).
+Sengoku BASARA (April 01)
+Slap Up Party -Arad Senki- (April 03)
+Hanasakeru Seishounen (April 05)
+Cross Game (April 05)
+Natsu no Arashi (April 05)
+Robo Crosser (???)
+Bakugan Battle Brawlers New Vestroia (???)
+Rainbow Nisha Rokubou no Shichinin (???)
And in the end the OVAs I plan to watch:
+To-LOVE-Ru OVA (April 03)
+Yurumates (April 24)
+Spice and Wolf II OVA (April 30)
+Denpateki na Kanojo (May 01)
+Dogs: Bullets & Carnage (May 19)
+Kiss x Sis (May 22)
