Excuse the stupid here (copping out by blaming the painkillers for my slowness)... so you're saying that Voldemort was going to the Potters to make the sixth horcrux because his soul would then be in 7 pieces but that, err, blew up in his face and so now there are really only 5 horcruxes plus that bit of soul that he couldn't finish using to make up a horcrux? Since Dumbledore and Harry destroyed two... there are now only 3 to go plus Voldie himself?

Also - how was Harry and Dumbledore able to destroy the Horcruxes if you can't do that? I'm sorry to be so slow on this.
