Caleb...you are spot on as to why Peter Jackson went with 48fps on The Hobbit...and it is disappointing that some so-called critics can't seem to understand something that has been so widely commented on in relation to 3D movies.
Personally, I couldn't care less about 3D. In the 5 movies I have seen in 3D, including the Imax version of Avatar, it has been a meaningless gimmick which has added nothing to the experience for me, even though I can see the effect and it doesn't cause headaches, eye strain etc.
But it is obvious the Peter Jackson and James Cameron are trying to improve the 3D experience, so good on them for trying.
On the other hand , I am very much looking forward to 4k2k projectors (in cinemas and for the home, as I have a home projector) and 4k2k TV's and monitors.
What the comments on this article and the related one that Andrew has posted show, there are some people who are very uncomfortable with the digital worlds domination in all aspects of movie making and display, be that cameras, projection, tv or anything else.
Whilst that is unfortunate, and obviously places like this give them a forum to express their unhappiness, the tide of history is against them I think.
And I certainly believe the changes are and will usher in far more benefits than problems or costs. Some of those used to doing things in the "old" non-digital way obviously are not happy having to learn new skills and practices, or seeing movies looking differently from what they have been used to.
Such attitudes are an inevitable part of any revolution, and what we are experiencing now is a very far reaching revolution indeed in the world of entertainment.
