I think the wedding will still go ahead, but not for a while. Vicky will end up winning the title back for Edge at GAB, by helping him distract HHH, and then they'll "fall in love" again. The wedding will be on again, Taker will come and trash it, leading to Taker vs. Edge at Summerslam.
Either that, or, they'll have a no DQ match or something with Edge vs. HHH at Summerslam, then Taker will come in. Can he win the title by doing that??
