There seem to plenty of guesses about this person here...I don't think its Neville, the face doesn't seem to be round at all. How about Colin Creevey? Is he the 'fan ' JKR was talking about? Maybe that's why he's on the cover.  And if the 'fan' is on the cover, I really really really hope its not Ron. I won't be able to take it!
 
My money is on the new DADA teacher, thought movie contamination might lead us to think spiky hair = Madam Hooch.
