There's also the issue that the Bro's came to kill Jesse on Walt's orders - but whatever happens to Gomie and Hank, obviously Jesse's going to survive this showdown.
However the writers manage it, I suspect we'll see Walt and Jesse working together for one final cook, even though neither of them wants to be doing it. And something that hasn't happened since the pilot episode is - a cook session going disastrously wrong. Especially if Walt sabotages it on purpose, as in the pilot.
Not sure if that's where we're headed, but there'd be a nice symmetry to it...
