Basically, I agree with what everyone here is saying about next week's episode, but here's why I think Jon won't go- they made it to obvious in the previews that Jon is annoying his tribe mates and that they want to throw a challenge. If Jon were the one to get booted, I'd doubt they'd show in the previews them talking about throwing a challenge because they want to get rid of somebody and then showing Jon.
As much as I dislike Morgan, I would sort of like to see them win, but there's one thing that's keeping me from wanting that bad enough- they act like there they better tribe, yet can't figure out why there losing. Plus, what Andrew said after losing the first IC ("remember how cocky they were when they won") makes me want them to keep up their losing streak even more. Like they wouldn't be cocky and in your face about it if they were to finally win.
Now about the "reward" at the IC. Maybe the losing tribe has the option of voting someone off or allowing the other tribe to take one of their members? Or that one of the 3 booted castaways comes back and joins the winning tribe. Which would be funny if Morgan can't handle the fire, water, or fishing without scoutmaster Lill, only to have her go over to Drake and give them an even bigger edge. I just hope it's not letting the winning tribe take another tribemate. Wonder if Drake would let Rupert take his spear.
