Even though this is a spoiler thread, I'll put what I've heard about the possible final 4 in spoiler tags:
Click to see Spoiler:According to SF, it said Coby had major hang time w/Steph, so if that's true, Steph getting booted is probably only a couple of episodes away. Because the only place they could get to have hang time would be the jury house. Also, SF speculates that Tom, Ian, and possibly Katie are all in the final 4. They seem to border Katie on final 4/5. Janu and Caryn are jury member's, which means Tom's alliance holds up for a little while. The only 2 who don't seem to have any placement that I've seen is Jenn and Gregg.
I think the possibility of Tom/Ian/Steph/Katie making the final 4 is a good possibility, but the only thin that could happen to break that is if someone pulls on upset on the challenge before the final 4. I haven't enjoyed this season since the premiere, so if it does turn into Pagoning (after the Ulonging) it isn't going to make it any more boring from where I'm sitting. I'll just be happy if Tom or Ian can take the game.
