Good news! The most egregious failure of the fansubbing world has been rectified. Dimension W's ova, which came out last year, is now available for viewing this year. I guess the next most pressing demand is the Fate/Kaleid Liner 3rei specials, but an entire ova > mere specials.
This is the last holdover from 2016 we were waiting for. From here on 2017 will have to make its own good anime. As nice as it is to have the complete Dimension W anime, it's still not out in blu-ray so rewatching it still remains impossible. Maybe someday.
