There might also be some fans waiting for the boxset of all seasons to come out.
Wow. I shudder to think how much a boxed set of 7 seasons on bluray would cost. I walked past a set of one season of TNG in Target the other day, and I had to do a double-take when I saw the price tag! But for some reason, I don't think I'd have the same reaction if I saw DS9 on bluray. I'd fork out the cash faster than you can say, "Dabo!"
