i think mebejedi makes some good points here about leia having more of a 'force-induced' memory of her mother. but i dont believe anyone had that in mind when the dialog was written, and it would have been just as easy to make the new film agree with the past ones, but Lucas just doesnt care enough about his own work to do that. im sure this whole thing has been discussed alot, but it really wasnt a problem until all of us saw the last 10 minutes of ROTS and said 'what the fuck, jesus christ, goddamnit'., and so forth.
