Anime 41-50:

And since I promised to extend things out to 50, I may as well do so:

41.  Mahoromatic
42.  Uuchu no Stellvia
43.  Utawarerumono
44.  Valkyria Chronicles
45.  Prince of Tennis
46.  Major
47.  Berserk
48.  Saki
49.  Claymore
50.  Zero no Tsukaima

I won't spend too long on these series.  Mahoromatic asks the important question, what is worth doing when you know you're about to die anyway?  Other series have their own amazing unique qualities.  In Stellvia, man has already overcome their internal differences, and are struggling with a much nobler, more heroic problem -- a supernova in a distant galaxy's radiation is projected to destroy mankind, and only a thin gray line of highly skilled pilots using supremely engineered high-tech countermeasures stands in the way of the end of mankind.  The story evokes the same feel as Ender's Game, but has some of the best songs ever sung, The End of the World and Brilliant Road, backing it up.

Utawarerumono is charming and funny.  Valkyria Chronicles' art style is just gorgeous.  Prince of Tennis and Major make you want to play tennis, and baseball, respectively, as well as admire the hard work of those who are playing, or who try hard at anything in their lives.  Berserk is a pretty grim, but always gripping, story of war and death.  Saki, meanwhile, is a story about Mahjong, but really about friendship and how hobbies can bring people of all types together into amazingly tight and powerful bonds.  Claymore is a lot like Berserk, but with more well thought out fights and artistry.  And Zero no Tsukaima is about how far a guy would go for the girl he loves.  The answer is, pretty damn far.  That answer alone makes the story well worth watching.  You'll know the scene I'm referring to when you see it.

As for the age of these series, most are in the 'within the last 5 years but not within the last year' category.  Major is an exception, having only finished a couple weeks ago.  Berserk says it will continue, maybe this coming spring.  As for the rest, there's plenty of additional source material if they wanted to go on animating the series, but it's doubtful anything will come of it.  Sort of like wishing for a movie version of Silmarillion.
