#2. Will the legends make their presence known prior to Saudi Arabia?

With just 11 days left for the Saudi Arabia show, WWE has their second last chance to have anything remotely close to a "build" for Goldberg vs The Undertaker. It's been advertised as a first-time ever "Dream Match" and in a way, it is, albeit way past both of their primes.
It's surprising that WWE hasn't had either competitor come out to make an appearance of any sort. We might get a token appearance from The Undertaker or Goldberg, but usually WWE prefers announcing those beforehand so that they can get higher viewership and ticket sales.
Look who just shut down all of Tony Khan's critics! More HERE.
However, for once, WWE could decide to pull off a swerve and have a surprise appearance from either of the two men. If both men had a staredown, then it certainly would be epic, but that's something that may be saved for next week.
