Being fairly new to the TV on DVD craze, and struggling to catch up, I've got a question... When the seasons of a show sell out, is there a chance the studios may release a 2nd/3rd/4th etc edition like book publishers? I almost didn't find Alias Season 1, and bought what may have been the last boxed set in town. CSI seasons 1 & 2 are still on my purchase list, but so many of these sets are expensive and can't all be purchased at the same time (I'm dreading September...) I've not purchased ANY of the Star Trek seasons (any of the series), but want to have the complete collection as I can find/afford them. The last season of Voyager and Enterprise will be purchased as they come out, I hope. Anyway, with continuing interest, does anyone know if we'll see sets come back out every few years? Sad thing is, my TV on DVD outnumbers the movies I own, and that percentage continues to grow!
