Seirei no Moribito was awesome...
Anyway, as for this, I haven't watched it, but I have read about all of the manga that's out for it, and I don't know how the hell they're going to make 51 episodes (anidb page) out of so few chapters... they're only at like 24 chapters right now; they'll have to keep making chapters, and damn fast...
Your only looking at whats posted on like one manga or a website that translated to english there are 11 volumes of this released and they have only translated up to part of volume 7 into english. I watched the first episode and liked it so I read the manga and liked it even more. I will be following this show for sure.
Oh, true, I didn't consider this was being made in Japan, not the US, and not from fansubbed versions of the manga, so they probably do indeed have enough material.
On the other hand, I just hope they don't fuck it up, and decide to screw the manga (though in some cases, that worked out; take Darker than Black, a great anime, but then when I went and decided to look at the manga.. and it was almost like it was in another world)
On a random note, I just realized that season two of XXXHolic's out and has been subtitled up to episode three. Hurray! <_<;;
... and then also noticed that Saiunkoku Monogatari's still dead... Hurrugh...
