As for the people who mentioned Walt and Jesse being shown... I don't think so. Remember, in BB Walt and Jesse just meet Saul, they don't know him.
If the show goes into that time frame at all they have to show Walt and Jesse. Remember when Badger was arrested? That is what started everything in their partnership with Saul. Walt went to pay for Saul and they started talking. So no, they more than knew Saul after that because he partnered with Walt eventually and I think he was the one that teamed Walt up with Gus as well. If they even go near current day Saul they will have to show Walt and Jesse.
