Having just watched the 10th ep of season 5, or the second new ep, i think that separating into team hank and team walt is a very accurate assessment.
i think basically its going to be everyone vs walt, but walt will somehow prevail then die from cancer. u can see hanks getting ready to approach jesse, who in his guilt ridden condition will tell hank everything, or possibly nothing, but still help him. i think skyler will turn on walt, and so will his son. lydia and todd and co, will turn on walt, and he will run off into the desert, as has been envisioned in flash forwards. everyone will find and confront him, and he will get out of it then die of cancer.
i know he will die, because theres something about censorship, a show like this would have only been allowed on tv, if they show the consequences of running a drug empire. Walk has to pay.
the question is how all this will exactly come into affect, and i dont know the answer. we can expect some great twists and turns, one of which will be jesse finding outit was walt who poisoned his gf's kid with that herb that on paper acts like ricin. remember when jesse told his gf to tell the codtor it may be ricin, but it turned out to be some flower, that at the end of the episode, was shown growing in walts backyard.
one thing for sure, is im going to love every minute of it.
