I was so glad when I read that HD versions are in the making. I've seen Kerr's book cuts I and II, and Sharkey's Purist cuts of TTT and ROTK, and I must say that they work. Less fluff, more true to Tolkien.

I am planning to re-watch ROTK Sharkey's Purist edition soon, which brings me to one issue I remember - you have cut the WK breaking Gandalf's staff, but if I remember correctly, after the horn goes off in the distance and WK flies away, we see Gandalf on the ground where he would have been in the un-edited version. Will double check this today.

I love that this scene has been put in in the extended edition, but no way should WK break Gandalf's staff or in any way scare him. Gandalf is the only one able to resist the terror of the WK and stands his ground ready to do battle, then the horn sounds and the WK flies away.
