Excellent, can't wait! I was eager to check out the saga in 720p in the meantime, I've previously only seen a bad quality version cobbled together from laserdisc/vhs, etc. Mainly wanted to see how good the picture is (seems excellent at just 720p, compared it to my blu-ray and aside from a slight colour difference it seems comparable) and how much has been edited for TV (as I expected, some minor cuts to some overly violent scenes like Don Ciccio being murdered, nudity and the one use of the "f" word, although thankfully Michael killing Solotzo and McClusky has been left totally intact).
I'd be quite interested in replacing any edited scenes with the ones from the blu-ray if I get time, there seems to be very little difference in the picture aside from a slightly more greenish tint to the AMC version (ditto with the DVD) which is barely noticeable unless you compare screens side to side, so switching between the two wouldn't be jarring.
There is also a Godfather Chronology fan edit (some of you may know about it) which compiles every known piece of footage (including from part III) into one 10-hour film. It's taken from laserdisc/dvd/vhs, etc though so quality is average and at times quite poor.
