Guys, I think he's explained why he did it and keeping the argument going isn't going to change things. It's called "Harmy's..." edition and he's free to do with it what he wants. It's the tiniest change that, I agree, most people wouldn't even have noticed if it weren't brought up in the first place.
I watched the WP several times (not completely, just different sections to see how awesome they were now) and never even noticed it. He's not restoring this so other people can use his version to make their own 'better' ones later on, so that point is moot. He wasn't commissioned by Disney to do a 100% faithful restoration for mass release to the public where something like this wouldn't be allowed, it's *his* version - for us.
The bottom line is - if you don't like it, don't watch it. Or better yet, if you don't want rounded corners on the version you watch, I challenge any of you that are arguing this point to roll up your sleeves and try to make a better one. Simple. :)
Keep going, H-Man! Can't wait for the final version to come out so I can buy it. Oh wait, that's right - it's free.
(P.S. Why are you even looking in the corners anyway? Watch the damn movie and enjoy it! LoL)
