Possible Trailer 2 date
I would just like to say credit to u/GameRollGTA on Twitter.
First off, in this shot, if you look at our player's arm you can see he has a tattoo, it has a magic 8 ball on top, in the middle there is "VI", and on the bottom there is 1 and 2. Now if we put it together it spells out, 8/12 VI, which could mean August 12th, 2024 for trailer 2.
Now this theory isn't insane either considering Rockstar has done this sort of thing before in the past before Trailer 1 released, I believe it was about a month before they released a shirt with a bunch of numbers forming around this diamond shape, and if you look closely in the numbers there is 1 line that is 12052309. December 5th, 2023, 9 AM ET.
Also, if we look in the past with major game releases for trailer 1 and trailer 2's, Rockstar hasn't done August yet, they've done every single month in the fall, and even December for the holidays. But not August, and considering that this marketing approach has been somewhat unconventional for Rockstar, why not release trailer 2 in August?
GTA 5 Trailer 1 - November 2nd, 2011
GTA 5 Trailer 2 - November 14th, 2012
RDR2 Trailer 1 - October 20th, 2016
RDR2 Trailer 2 - September 28th, 2017
GTA 6 Trailer 1 - December 4th, 2023 (meant to be December 5th)
Edit: forgot to mention that there's also an earnings call in August close to August 12th, and considering they like to announce and release stuff before earnings call would make the most sense. This adds further credibility to this theory.
