For being a perfectionist, he sure let a lot of crap go when he fixed Episode IV for the Special Edition. All of the jump cuts are still there, the lightsabers still looked terrible, Obi Wan's still looks like the batteries are dying in one scene, etc... He also missed quite a few of the snow speeder scenes when he re-matted them in Empire. Some of them looked great - others he completely forgot about I guess, because the semi-transparent dashboards are still there in the special editions. Not to mention totally botching Han sliding out of the way of Greedo's shot. That looked like total crap.
Perfectionist? No. Absolutely not. And even if he was, creating the right eye out of thin air is no small feat. I'll be impressed if he pulls it off successfully, but I'm not holding my breath.
