As previously reported, the plan for the upcoming WWE Survivor Series pay-per-view is to book Randy Orton vs. Big Show for the WWE Championship. The reason it seemed like WWE was pushing a Big Show vs. Triple H match once again on Monday's RAW is because the plan is for that match to headline the WWE TLC pay-per-view in December.
Obviously plans could change as time goes on, but as of right now, that is what's scheduled to happen.
