^That was odd.
Anyway, I think Edge/Jericho should be the main event. I don't think Taker/HBK needs to be the main event in order for it to seem big. As long as they don't do what they did with Michaels/Flair and follow it with Snoop Dogg introducing the divas, it should be fine anywhere on the card but I suspect it'll be the second or third last match.
The WM main event should be for a title and seeing as Edge won the Rumble, I think it'll be on last. Maybe the MITB winner will come out at the end, ruin the celebration and pin Edge for the title. That would be an ending (depending on who the MITB winner was of course.....).
