Someone's gonna die. Will they become a ghost?

I was thinking this recently... it's a well known fact that 
*someone* is going to die in the next book, and probably more as 
time goes on... so what do you think the chances are of the person 
who dies becoming a ghost, and sticking around to help people?  I 
mean think about it... didn't JK Rowling say that the happiest 
people don't become ghosts, and that we'd learn more about that in 
future books?  If the person dies is Lupin or Sirius, they're 
definetly not happy.  The same probably goes for other people.

This is just an idea I was thinking about... I don't know much about 
ghosts.  Can ghosts go to other places... wait, they must be able 
to, considering Nearly Headless Nick's deathday party... could 
someone become a ghost and spy on other people, like Voldemort?  
Yeah this is getting kinda crazy... I just have this idea of 
someone, maybe Sirius being killed, but still sticking around to 
help everyone else, and spying on Voldemort and stuff because he 
can't be hurt.

Please respond.  I'd like other opinions on this.  Sorry if it's 
been discussed before.  And one other thing... I think too much... I 
was thinking this morning, do you think Moony, Wormtail, Padfoot and 
Prongs deliberately let the Marauder's Map get confiscated when they 
left so that other people would be able to use it after them?  Not 
very important, oh well...

Have a nice day!

Peace,
