* Big E. Langston vs. either The Big Show or Mark Henry. More than likely it'll be Mark Henry. Expect that feud to begin on RAW next week with Mark Henry returning as a babyface. They could also add The Big Show to the match making it a triple threat match between the three "big men".
* Rey Mysterio vs. Dean Ambrose. Mysterio is expected back sooner than later.
* Other potential feuds for the summer, but not specifically for SummerSlam, are rumored to be Randy Orton vs. Ryback and Rey Mysterio vs. Jack Swagger.
