While on this topic, I'd even say Padme should not be seen giving birth to the twins in ROTS:R. I think it was intended to be another surprise in ROTJ when we find out Luke has a sister (not as big of a bombshell as Vader to Luke in ESB, but a surprise nonetheless). If we see the birth of twins, even if their names weren't given, by ANH the audience will know who Luke is and likely predict who that sibling is early on - not good.

Yeah, I completely agree with this.....I would very much like to see many of the OT surprises preserved in the PT.
