Berserk has been one of the most frequently talked about titles as far as sequels go (the other one being Hellsing, but that wish is finally being fulfilled ^_^). The unofficial word on the street was that they stopped so the manga could continue on and they could work off of that (because they had caught up to the where the manga was rather quickly). However, the anime covered the first 17 volumes or so and they're now around volume 30 in Japan, so there's more than enough material for them to continue on with the second season. Still, though, there hasn't been any new info about it. It's also been rumored that they've been waiting to do a second season until the manga is
completely finished but, like I said, demand for a sequel is huge so...be wary of anything you read about it online; most likely it will be fan speculation. Unless, of course, you see a press release, at which point the anime community will probably be jumping for joy.
