The next anime TV Series to air in Japan in April is Last Exile. A bunch of screenshots and a streaming trailer is at the site. Must say.. if looks kill, then I am zombie while typing this.

Another nice looking anime comes from ADV and directly from them. Mutineer's Moon is a 26 episode series based on books of science-fiction writer David Weber first book in the Dahak Trilogy. The site contains a lovely array of graphic art to be used in the series. As the site says ...
will be the result of a partnership between artists and production groups all over the world.
... which means an excellent array of thought and ideas will go into the series.
No trailer or word on release yet.
