think about the potentials now.
Mike is doing dirt now... they can invent any adventures for him.
Saul will have some legit lawyer success.
Saul's brother will recover and inevitably die at some point.
That blond chick will get fired, work with saul, have a love affair and breakup.
The myriad of bad guys from BB can come and go as needed. HANK can show up! fans woudl shit their pants if they crossed paths. hank's partner will probbaly show up first, I'd guess. Gomey.
Gus will be epic. Seeing Polls grow from 1 store to 14, seeing him buiild his network.
Brian Cranston is too much of an egomaniac not to do a cameo soon

Jesse too... his movie career sucks, get him in there, interacting with mike or something.
Those bald twins can visit with Tuco. the dealer tied to the pole that Walt choked out crazy 8.
And their braintrust had years to plan how they'd do it... there are going to be lots of easter eggs, I'm hoping.
