Well that settles The Hobbit for me. If the green tint is theatrically accurate then the BD is perfect as far as I'm concerned. Personally I don't care much about the green tint in FOTR EE since I much prefer the theatrical versions of all the LOTR movies but, as always, I'm glad there are fans out there with the skills and dedication to put these things right for people that want the choice.
That's interesting about movies being delivered on HDDs. I had no idea that's how things were done nowadays. :)
