I just would like to think the WWE does start with HBK but knowing GOD. He will have to end the show with him, because his feud is so ever important. Do not get me wrong HHH good competitor just sick of him hogging the spotlight with 20 minute opening segments, that could easily be directed to us in about ten minutes. I just feel with Mania coming and GOD vs Undertaker being a main match at Mania. It would be a main focal point for the show. Also they probably want to get that nice over run for the huge late night rating.
Triple H vs. Undertaker is THE biggest match at this WrestleMania, at least I think so. Rock vs. Cena is huge, but it's not like it's the last match for either of them
Most likely, this is it for the Undertaker. The one guy people have watched 19 WrestleManias for. It should be the focal point, by far. Rock vs. Cena just doesn't compare to Undertakers last match. It's a much bigger event.
