Huge Hellsing fan here, and I just got finished watching the new Hellsing Ultimate OVA DVD that hit shelves today. Really love how the series has been reanimated and storylines have been shifted to better follow the plot points established in the manga lore. Although there is a standard edition of the Hellsing Ultimate OVA available, I went with the 2 disc limited edition that includes about an hour of bonus material for the series. You can find out more about it here: http://www.hellsing-ova.com/
Pretty cool fan site that I've become accustomed to visiting. Enjoy :P
