The theatrical cut of TMP alone is worth the money of the box set, considering that it's last release was on VHS. It could only be topped by the SLV! Regarding 4K, I'm asking myself: How much resolution do we really need? Would it make a difference big enough on a normal tv set to convince people to buy their favorite movies yet again? I don't think so. To be honest, on my 32" tv set even the BDs look only marginally better than the DVDs, so 4K wouldn't improve anything for me.
