Wow, I actually broke some news first for once... Yay me!

After watching the trailer, I personally didn't notice changes... Not sure what's going on really still, but I'll be excited to see that 4th DVD with the bonus stuff at least.
I really wonder if Lucas isn't just holding off for a full 6 film set someday or something. I have to admit though, I'm anxious to see what (if any) changes are made at this point.
