It sounds good, but Rey is injured and word is that he wants to work a program with Cody Rhodes after the rehab. Rey apparently wants a Wrestlemania match with him, and will possibly put Rhodes over at 'Mania or Extreme Rules. That sounds like it would be pretty cool, so the Kingston/Mysterio thing would have to wait about 3 months.
Either way, it could be a really nice series but I don't see how they book it without Mysterio as champ of a Kingston heel turn, both of which seem unlikely.
