Case Closed does sound like a good deal. Does the show's uncertain future mean that a Blu-Ray release is unlikely?
There probably won't be any Blu-ray versions of the tv series by Funimation. Funimation has gone on record stating that they're not planning anything else with the tv series, as the season sets have sold horribly. They just did the same thing with the When They Cry & Familiar of Zero season sets. So just consider what is released the only tv series stuff they'll release.
The movies, on the other hand, have a chance. Since those have sold decently. Plus it's less work for Funimation to transfer them to Blu-ray, as the Blu-rays of most of them have already been released in japan.
