Rating: - Season 5 Will Come
Where is season 5? It's waiting for Fox to sense money in it. No studio is going to release anything just to be nice to its customers. They don't think the same way that other consumer-oriented companies do.

Be patient: most TV shows will eventually be released on DVD. Right now, the studios (like Fox, Universal, etc.) are caught up in the Blue-Ray / HD format wars. They are desperately trying to feed their bottom lines with new movie releases of previous DVD releases, but in these new formats. Neither format is likely to survive. Further, in a very short time period, all movies will be readily and cheaply available for download on the Internet. The destruction that the CD music industry saw is within years of happening to the DVD, or any movie-on-disk, industry.

TV shows are different, especially older shows. People want to own the physical copy. A season of shows is too cumbersome to deal with unless it is organized as a complete unit and the ability to select a particular episode at whim is highly valued. In fact, TV shows are becoming a more important part of the DVD production agenda. You can see the stream of new releases every month. The studios will reach deeper and deeper into their vaults of TV shows, particularly as movie demand begins to dwindle.
