  Okay... here's a theory.  DD knew that the horcrux wasn't in the basin in the lake.  He deliberately took Harry off Hogwarts grounds in order to let Draco get on with his assigned task from LV.  He knew that Madame Rosmerta saw him and, IMO, knew that she was already under the Imperius Curse.  By taking Harry and himself out, he was basically opening the door for the DEs to enter Hogwarts.  I am sure that DD knew that his staff (and DD's Army)  would provide adequate protection for the school -- this was proven since none of the "good guys" died, partly due to the Felix.  
   
  Anyway, DD went to the tower, under the Dark Mark, knowing this was where the action would be happening.  Draco came in, wavered in his execution, allowing Snape to come in and satisfy his end of the Unbreakable Vow.  This ties in many threads going on right now-- DD was asking Snape to kill him, how was Snape going to get out of his end of the UV, and/or DD was already "partly" dead.
  
My hypothesis is just that... however, I think that Book 7 will show that DD will be of use to Harry in his current, picturesque form.  Maybe Harry will keep a DD Frog card in his pocket for later help... I don't know... but thought I would offer a theory!  Feel free to tear it apart!
   
  Melissa, who is still holding out hope that DDM!Snape is really DDM!
