-- The latest word on the Sin Cara character is that it indeed will be FCW star Hunico wrestling under the mask at tonight's SmackDown! tapings. The original Sin Cara will return once his suspension is over and a feud with Hunico may end up happening on WWE TV.
-- Regarding SummerSlam only having four matches announced, word is that as of yesterday, that's all the matches WWE had finalized. Creative had more matches lined up two weeks ago than they did yesterday at RAW. It's expected that two or three more matches will be added but there's also talk of having longer matches than usual.
