Currently, I have every trek movie and series on DVD, as well as almost all DVD episode collections, and Star Tre 2009 on Blu ray. Fortunately, the only VHS Trek I replaced were the movies, as I never purchased the episodes on VHS. Now that we are starting to see the movies and various series starting to be released on Blu Ray, I am curious how many people previously purchased Trek on VHS and DVD, and how many have purchased on Blu Ray. Also, of those who have or bought the Blu Ray versions, still have their trel VHS or DVDs. Finally, how many people will not because they already have Trek on DVD or even VHS.
