Okay, I (finally, like 2 months later) looked over most of those, and I'll just give my two cents (all items are ratio'd according to Want/DONOTWANT[to watch] percentage ratios)...
These are the ones that seem interesting (90/10, maybe higher) to me:
1. Durarara!! - I
liked loved Baccano!, and I sure as hell am not going to overlook this.
2. Katanagatari - definitely like the art style, that girl in the picture with him looks quite cute, and from
what I've read of the description on anidb, this looks like a very interesting show. Since they're going to put a romance plot in it, too, I'm all in. I seriously doubt it can be something like Seirei No Moribito (it's hard to match that level of quality), but I hope it does something good.. in its own way. Plus, according to anidb, it looks like it'll be aired once a month, for 50 minutes. That tells me that they'll have a lot of time to put some serious quality into this show (I hope).
3. Nodame - I liked the first season a lot. Second season is kind of boring me slightly, but the main reason I haven't finished it is because the series didn't have an ending at the time. If this is gonna be a good finale, I'll finish up the second season and get this thing done, too.
Things that I'm 70/30 (Hmmm.....) on:
1. Ookami Kakushi - Higurashi was okay, sure. While I did defend Umineko, I'm definitely going to say that it probably wasn't as good as Higurashi (not that I thought Higurashi was THAT great anyway). Therefore, I'll probably watch this out of interest, but I'm gonna go ahead and say that it might be a flop. Besides, to be honest the Higurashi formula is kind of getting... eh... boring. Still, it'll probably be at least somewhat interesting. Who knows, maybe they'll turn it into something better than Higurashi.
Things that I'm 50/50 (Ehh...) on:
1. SoRaNoWoTo - Lol @ wartime music. Can't really say anything about this one until I know exactly what the hell they're gonna do. I can say that there is one big reason I'm not going to enjoy this as much as I could, should I watch it:
change in art styles. Originally, this was going to look kinda like
like it does in the anidb picture for the art style and character designs... but they decided to fucking K-Onify it. I liked K-On's art style...
in K-On. I absolutely fucking loathe the changes they made to this title. That alone makes me drop this rating. It seriously pissed me off.
2. Dance in the Vampire Bund - Umm... To be honest, I read about 13 or so chapters of the manga... and surprisingly this is more generic than I thought it would be. It's a bit unique, but I felt like I've actually seen this general type of storyline before. Therefore, I'm probably not gonna get my hopes up too high for this one; not that it'll be bad, but I don't think it'll be that great.
Half the reason I think this may be a popular title is because there's a nearly naked loli... and sadly, I'm not joking when I say that.
The Meh Stuff (30/70 and below):
1. Qwaser - Let's just say that I think that this may end up being a generic shounen and leave it at that. The ratio of watch/DONOTWANT for this one may actually be a good bit lower than 30/70.
2. Omamori Himari - (0.1/99.9) I just actually wanted to say that I've already read a lot of the manga for this one. Definitely generic harem shit going on here. Don't waste time on an anime version.
Everything else is almost on a 0/100 level.
