Actually, the deleted scenes might look better because they weren't copied endlessly and handled as much. By simply being left alone, they might not have suffered as badly.
I agree with the Don't Buy it. Aren't the deleted scenes from the prequels still on youtube? You know they will be posted eventually and I'm sure you could rent the blu-ray to watch them once.
Other than that, It's A TRAP!
If the OT does indeed use the same 2004 master, then that should be pointed out as much as possible and emailed to people like Bill Hunt of the Digital Bits with screencaps for comparison.
