John Cena Added To All Smackdown Tapings Post HIAC (CM Punk As Well)
http://www.wwe.com/events/all/all/all/all/all/3000/mi/page-3
not yet advertised but also CM Punk is supposedly expected to be added a few Smackdowns too during Survivor Series build (due to the European Tour)
reason for this because Cena & Punk (along with Del Rio, The Wyatts, Heyman, Ryback, Axel, etc.) are going to headline Smackdown House Shows meanwhile Orton, Bryan, & Big Show expected to headline the RAW house shows on the European Tour & After as well. Orton/Bryan/Big Show still advertised for all Smackdown (except 5th & 12th due to travel & working other house show)
EDIT:
