Heh, definitely a major glitch there as Harry gets entered again (though it should be somewhat easier for him this time). I have to say I love your term for Snape, "The Dark Prince", and I'm certain he won't care at all for it. Malfoy as "the real Hogwarts Champion? Hogwarts is doomed this time. On the other hand, 'twill be interesting to see who did enter Harry and how/why. 'Tis going to be a very interesting year, no matter what Harry does.
Oh, I admit that I love how he controlled Yaxley into those admissions; I can see the 'establishment' getting rather shaken up as Madame Bones cleans house.
