Links to some theories and predictions
Predictions and theories from adaptor. A couple are quite old (and pre-HBP) but still very well-written and entertaining, especially for Snape fans. Or maybe just for people who weren't in the fandom until after HBP was out (like me).
Predictions for Half-Blood Prince - why the "half blood prince" has to be Snape.
The Snape is a Vampire Theory - or at least half-vampire. (No, really.) Written February 2005 (before we knew more about his parents), but still yummy.
Predictions for Deathly Hallows: First part is Horcruxes, then Snape. I am starting to think these are pretty good predictions (though part of it could be wishful thinking).
