Either way you are still paying for two discs, and I don't feel like paying for a second disc with a trifling amount of extras.
I've seen the movie several times in theatres already. As a film student, getting some decent special features are a big deal to me. I doubt fitting all of the extras on one disc would've comprised the picture quality much technology being what it is today and New Line releasing the extended versions of LOTR on one disc while still having decent picture and sound quality.
Sure you want the movie, but I see no point in getting it now, when a superior DVD set will just be released later down the line and people will complain about the studios taking your money. I'm simply playing it smart now, and I really just want to watch it on DVD, I can always rent it.
