WWE SmackDown - 5 Surprises that could happen- Big wedding gets confirmed, Roman Reigns confronted by former Champ

#1 The entire RAW roster runs through the WWE SmackDown roster in the main event

To get you in the mood for Survivor Series, we caught up with WWE SmackDown superstar Seth Rollins who had much to say about The Undertaker and what the legendary Superstar means to Rollins as an influence. The Undertaker will bid farewell to us all at Survivor Series and the WWE SmackDown discussed the legacy of the legend with us.

But coming back to the point at hand, could the RAW roster run through WWE SmackDown in the main event, to build up to Survivor Series 2020?

Thus far, the only inter-brand element we've seen in the build to the pay-per-view was Drew McIntyre's little cameo on WWE SmackDown. It may be time to amp things up with a proper invasion so that people are keen to see which team gets the upper hand at Survivor Series.

One hopes that this surprise is a certainty because if it doesn't happen, Survivor Series may not seem like a very appealing prospect.
