I took advantage of the Target Deal also. This was perfect for me, because I like Blu-ray/DVD combo packs, and the five-disc/two-movie pack strangely omits the DVD version of the original Tron, which is included on the individual release.
To me, this sounds exactly like the justifications we used to hear from people who complained about widescreen DVDs because they were more concerned about "getting the most from their TV" than about how images can be used to tell a story & how well the DVD reproduces those images.
