— Undertaker will return to television by crashing the wedding between Edge & Vickie Guerrero scheduled for a SmackDown taping in mid-July. He will then be plugged right back into his program with Edge and feud with him for at least the rest of the summer. If they don’t have a match at The Great American Bash, then definitely at SummerSlam, although it looks like the wedding is happening before GAB, so they could hotshot it for that show too. There was a feeling that his feud with Edge needed to be put on the shelf for a little while, although he did have some nagging injuries to tend to. The feeling was that it was going to run out of steam without a major twist, hence the retirement storyline.
— As noted earlier, despite his “retirement,” Undertaker worked SmackDown’s tour of Australia and New Zealand this past week. The decision for him to retire on television was a last minute move, but he had been advertised as the top star on the tour, so they decided to bring him on it. Tickets went on sale several months ago and the company drew huge advances everywhere, so a lot of fans were expecting to see him. The storyline explanation for his appearances on the tour has Shane McMahon coming out at the start of shows to say that he was talking with Vickie Guerrero and they agreed to let him have an “Undertaker farewell tour.”
