As much as the deleted material intrigues me I see no reason to purchase the set now and first hand just to see them.
I doubt if they will turn up for a while on Youtube etc and if they do I'm sure Lucas' people will have them removed as soon as they appear but eventually they will be free to view just as all the other officially released ones are if you know where to look.
I imagine the pre-existing PT deleted scenes weren't put out again because the effects to 'finish' them may not (and I welcome correction if I'm wrong here) be in HD.
Which would be consistent with the sort of short term thinking I would expect from Uncle George.
It seems astonishing to me that AOTC, which was billed as the first entirely digital mainstream release when it came out on DVD, has such shoddy looking and incomplete deleted scenes.
Surely that footage would be stored in pristine order somewhere (including all the See Throughpio stuff).
Maybe Lucas isn't always thinking short term and is saving further goodies for future releases which makes the "Own Every Moment" moniker of this set even more of a joke than it already was.
