Jeritron pretty much hit the nail on the head.
As much as I think HBK should go to SD, it will never happen.
With the way Jericho is looking now, he will always play second fiddle to HHH and Cena. Seeing him go to SD would be big.
Imagine if both HBK and Jericho went to SD....*dreaming* HBK and Jericho feud over the title
For Punk, I'm pretty convinced he is going to SD full time after mania. I mean I know Tuesday nights is pretty much The Punk Show, but there isn't really much left for him to do over there. Him in feuds with Matt Hardy and MVP would be great tv.
