At least one more match is expected to be announced for this Sunday night's WWE Elimination Chamber pay-per-view. The pre-show hasn't been announced yet, but WWE hasn't gone without one since they began airing the Kickoff shows. The panel is expected to be announced on RAW and SmackDown this week.
A tag team title bout with the New Age Outlaws defending against The Usos will probably round out the main pay-per-view card. There was reportedly talk of having AJ Lee defend the Divas title against Naomi, but due to Naomi's injury, those plans the match have been scrapped or been delayed. Original plans called for Naomi to win the Divas title heading into WrestleMania 30.
The expectations are that Randy Orton will retain the title going into WrestleMania, and WWE will still go ahead with his match against Batista as planned. Creative plans for WrestleMania 30 are said to be constantly changing. According to one source, "anything is possible at this point."
