gotta 100% agree with you on this one ,its one of the best "sengoku" type of anime i've watched, it doesn't move the story forward with the ecchi-ness like a few other "sengoku" animes i've watched.I liked Oda nobuna no yabou the most this season (if u don't count SAO) ,and i do hope that with the current sales of it's blu-ray and DvD it would have a second season, seeing the last part of final episode has a nice final pic drawn with a "see you again", compared to the other recent anime which ended with the ending theme.
Do hope to see more of it in the future, and i also do hope that more LN to anime adaptions can be like that too.
