With more and more television shows being released on DVD, is it possible that there will be an over saturation of new releases which in turn may lead to poor sales of some series (too many to choose from and can't buy them all)? I'm so far behind with my purchases now that I'm not sure I'll ever catch up. My concern is that a very high supply and not enough demand may cause slow/poor sales, which in turn may lead to the cancellation of future releases of season sets of some shows. Obviously, this leaves incomplete series sets. Anyone else concerned about this?
