I like the digital bits review,

regarding the deleted scenes :

I've now seen many of the Original Trilogy deleted scenes. No... I can't tell you much about them (believe me, that drives me as crazy as it does you). But I was pretty surprised by them and in a good way. What I can tell you is that they are substantial - at least for the Original Trilogy. This isn't just dribs and drabs stuff - it includes long sequences. And they're extremely cool. Frankly, for me this is the real draw of the entire BD release. As you've seen in some of the teaser clips Lucasfilm has released, they're not pristine, but most of them are in HD - at least the Original Trilogy clips. And trust me, they're well worth seeing. It's stuff some of you have wanted to see in good quality since 1977, along with a few things fans may not have known even existed.
