I've felt much the same way. I don't really know if it's my changing tastes but I've been sick for two solid weeks with pneumonia, and all I could do was lie around and watch TV, because it hurt to read, I lacked the mental agility for any of my video games, and there was precious little else to do. So I thought I would watch some of my anime, but as I scanned my collection I just marveled that out of the 24 different series I own, I didn't want to touch a single one. I also haven't been acquiring as much, mostly because it seems like the modern stuff is so much shit.
I also read Berserk, but have been debating whether or not it's worth it at $12 a pop every few months. And let's not even talk about Blade of the Immortal, which sees a printing every 1-2 years. I'm kind of in the same boat, waiting for Black Lagoon 3 and following my few manga series, and that's pretty much it.
I will say though, if I hadn't lent out my copy of DP I probably would've at least watched that.
