Based on this info, I'm gonna make a call.
Jesse, Skylar, or Walt Jr die next week at the end of the episode, and Ozymandias the week after is about Walt finally breaking from too much and going ballistic, he messes up, gets revealed, and disappears into Garden State.
So, I've been re-watching seasons 2 & 3. In the third episode, "I.F.T.", where Skyler is calling the police, threatening to tell them everything if Walt doesn't leave, Walt's response is:
"Do what you have to do Skyler. This family is everything to me, without it, I have nothing to lose.
Every episode towards the end of season 2 gave more and more glimpses into the plane crash; always focusing on bear, evidence being picked up, etc--making it appear that something terrible had happened at the White house. While it was a terrible tragedy--arguably Walt's fault--the appearance of what it could be, was actually something completely different, which makes me wonder if they're doing the same this time around.
The show has always been centered around family...that leads me to believe he's going to lose a family member, next week. I know Jesse is important to him, but important enough to push him over the edge, go out and purchase an MG, and then blast everybody? I doubt it...
The most valuable asset to Walt is, and has always been, his family. He appears to be a man with nothing of value left, with little to no regard for his life. This to me spells trouble for his family...which has always been a theme throughout the show. I think he's going to lose his family. I could be wrong and I hope I am but...seems to fit.
However, this show is so impossible to predict, I could be way off...but as with Season 2 revolving around the foreshadowing of the plane crash--and not knowing exactly what happened until the finale, I think season 5 pt II will be the same.
