Personally I like all three of the confirmed changes. I agree the digital Jabba in The Phantom Menace looks much better then the one in A New Hope and I like that the effect is going to be fixed. Like I said fixing the lightsabers would have been one of the first changes I would have made if I was improving the trilogy. The Emperor change I am kind of neutral towards. More changes I would like.

1. Restoration of original Han and Greedo scene

2. Deletion of black matte line around the racor.

3. Han should not step on Jabbas tail.
