This was true even back in the old VHS days. In the UK we saw several series released on VHS 2/3 episodes at a time which then stopped to become season sets, The X-Files for example or stopped entirely (mid season) Lois and Clark, Darkskies, Millennium. Liberation made a bit of a mistake by letting people know full boxsets were coming, maybe some of us were holding out. On the other hand, do casual buyers really know what's going on? I doubt it.
