Vampire Diaries List of Speculations

In honor of the last new episode of The Vampire Diaries until March 25, here is a list of my speculations:

1. Katherine is not in the tomb.
2. The remaining vamps in the tomb are all dead.
3. Katherine turns Stefan and Damon during their rescue attempt. They drink her blood and are killed, maybe even by their father...only to become the undead.
4. Emily and Katherine had a deal that preceded Damon's deal with Emily.
5. Emily was always loyal to Katherine and the reason she didn't want the tomb opened was due to Katherine not being there.
6. I do believe it is possible that Emily had a change of heart and mind, but I am suspect.
7. Katherine won't live too long after the tomb resolution.
8. Pearl and Anna escape and will return to Mystic Falls one day.
9. Alaric's wife Isabelle is a vamp and possibly under Katherine's control.
10. Maybe Damon actually kills Katherine to save Stefan or Elena?

How far off am I?
