I finally got a chance to watch Superman Returns and I really liked it and is definitely on my HD-DVD wishlist. However, I am also a huge fan of all 4 previous Superman movies. My biggest fear is that I will buy SR, S1 & S2: RDC on HD-DVD only to hear 6 months from now that all 6 Superman movies will be released in a boxset and #3 and #4 will only available in the boxset (ex. Mission: Impossible Boxset). What should I do? Should I buy all 3? Not buy all 3 and wait for some kind of boxset? Only buy SR? AHHHHH!
