I remember seeing that in the theaters and one my friends with me said "unacceptable.." during that sene.
Also since the last Indiana Jones movie was set in the 50's is this one going to be set in the 70's? Indiana Jones and the Boogie Knights Maybe they could have a real meta scene where Indiana Jones goes and see's Star Wars.
The only proof I have is I wasted money on it in the theater, and it was a very bad decision. Looking back I would have been better off walking out and at least getting my time back. Not a very good argument on my part, so I think trilogy sounds good, especially if all these test endings bombed for the newest dumpster fire.
