SKurj, when Lucas started starwars 1977 The book was allready
there, u know they didnt had render farms and the high tech to
visualize the huge battles in EP I and EP II, thats why he started
with Episode IV. The EP IV story didnt have any big battles to
visualize, only problem was Jabba the Hutt

(remember the
cut Han Solo scene).
And today it is possible to visualize huge battles so thats why
he started with the first episodes now. But i think the battle at
for Deathstar (EP IV + EP VI) and the Ground battle on Hoth in EP V
would look complete different if he would film it with todays
technology.
I hope to see less mega visual FX in EP III. EP II was on the
way to get overFX'ed. But thats the famous clone wars they
talked about in the old Episodes

You maybe wonder why no
Droidicas seen in the old Episodes ? well they were there, just
not on Tattoine or any other planet in the old Episodes

I'm really interested to see how will Lucas create the transition
from EP III to EP IV. I think we will see the Star Destroyers
and TIE fighters Designs from the old Episodes in EP III.
