I completely agree.  Snape is such an important character that I cannot imagine we will not 
learn more about him.  It seems ridiculous to think that J.K.R., who mentions Sirius Black 
in the first chapter of the first book, has not already provided us with more background 
than we realize on Snape.  My own pet theory is that he is the estranged son of the 
greasy-haired Mr. Borgin, proprietor of Knockturn Alley's Borgin & Burkes.  Obsession and 
great knowledge of the dark arts?  Inferior status to the likes of wealthy pureblooks like 
the Malfoys?  Greasy hair?  And why else are we aquainted with Mr. Borgin?
