Will Christopher Hitchens Go to Heaven?

Reading "American Grace, How Religion Unites Us and Divides Us" by Robert Putnam of "Bowling Alone" fame and David Campbell.  In one section  they cite a poll showing that most people think most people will go to heaven: that is, most Catholics believe Protestants can go to heaven, believe Jews can go to heaven, etc. So Americans mostly are tolerant and don't hold strictly to theological teachings. At least, that's what Putnam and Campbell say.  But I note the survey didn't think to ask whether atheists and agnostics, like maybe Christopher Hitchens or Albert Einstein, could go to heaven.  I wonder what such a survey question would reveal: is entry to heaven based on the life one led or the beliefs one has? I also wonder who will get into the heaven which features 76 virgins?  Is heaven segregated by belief?
