As mentioned in the post above, it is only on video. But I will tell you exactly which scene. Go out and buy the Empire Strikes Back DVD and play it with audio commentary by George Lucas, Irvin Kushner, etc.
In the duel between Vader and Luke on Cloud City, right after Vader directs Luke to fall into the carbon freeze chamber, the audio commentary has George Lucas saying,
"At this point, Vader's plan, now that he knows Luke is his son, is to convince him to come with him and join the dark side, and together they're going to overthrow the Emperor, which is the thematic device used through the whole movies, in terms of Sith, which is if you have Sith Lords, there's usually no more than two, because if there's three, then two of them will gang up on one of them, and try to become the dominant Sith. Anakin would have been able to do it, if he hadn't been debilitated, and now he's half-machine and half-man, so he's lost alot of the power of the Force, and lost a lot of visibility to be more powerful than the Emperor. But Luke has it, Luke is Vader's hope."
Additionally, another quote from George Lucas:
"Anakin wasn't what he was supposed to become. But the son could become that."
This is from the Rolling Stones magazine interview of GL, i believe.
If you still can't choose to accept it, go ahead and email GL to be sure.
