Jeez man, think about how many times in the past year we've seen Big Show vs. Lesnar, Lesnar vs Angle, or Angle vs. Show. They've really used up those matchups at the top of the card, haven't they?
I really think they'll do an extended Angle/Eddie feud for a few months. Cena should be the US champ, and I read that Big Show will need to take a few months off for (knee?) surgery. That leaves Cena without a really good feud, because they won't have Lesnar feuding over the US title, IMO. They did the right thing in elevating Eddie, but they need to elevate more talent as well...or, like you said, bring over a few RAW guys that aren't kidding much of a chance to shine there. Angle/Cena can still be turned into a lengthy feud, and I guess it's possible that Kane comes over to SD with Old School Taker too. I guess we'll see.
