Metropolis (1927) - I'm totally confused about what its running time will be?

[bluskies]

I am wondering how long the restored Metropolis is supposed to be when it comes out?

I've read various things:

Most reports say that the print that was found in Buenos Aires in 2008 has about 30 minutes of missing scenes.

Turner Classic movies says in one article, "This nearly complete copy of Lang’s 204-minute original now stands as the authoritative version of the film, according to the Murnau Foundation..."

Another source says Lang's film original was about 2 and a half hours before it was cut, and since the recent version was about 120 minutes, so with the return of the 30 minutes found in Buenos Aires, Argentina in 2008, it will be 2 1/2 hrs.

And then Wikipedia says, "On January 10, 1927, a 153 minute version of the film premiered in Berlin with moderate success." So where are people getting 204??? And yet, in the same Wikipedia article it says, "On July 1, 2008, film experts in Berlin announced that a 16 mm reduction negative of the original cut of the film, which runs over 210 minutes in length and features many lost scenes, had been discovered in the archives of the Museo del Cine (a film museum) in Buenos Aires."

If 210 minutes was correct, then that would be 90 minutes more than the 2001 restored version, not 30 as keeps getting mentioned. 210 minutes equals three and a half hours, not two and a half as is claimed as what was originally premiered in Berlin.

Do you see why I am confused? Somewhere, somebody is wrong about something.
