I read about them debuting the first 10 minutes of ANH in 3D at some convention about a month ago. If I remember correctly, you don't need glasses to view it. This would simply be a conversion, I don't think George would really be involved much. It would just be handing it off to some third-party company to convert them (there was another article somewhere that said the company Lucas wanted to use). I highly doubt there would be any changes for this version.
