AICN reports that the now defunct Firefly will most likely be released on DVD with the last couple un-aired episodes included. Not only that, it will probably have the episodes *gasp* in the right order!
That's not official confirmation or anything but it seems pretty likely. Who knows, maybe DVD sales will be high enough to encourage another network to pick it up..
No release date yet, but Fox Home Entertainment will be releasing. It sports the entire season, including the unaired eps, in 16:9 glory and, most likely, in the "correct" order. With lots of goodies.
