All it takes is someone who owns it to dump it on 6.72.
Trust me: it should drop soon
I think it could as well take some time. since someone has to meet the following criteria:
- Owning a PS4 that came with a Firmware 6.72 or lower
- Having logged into PSN to get Beat Saber before an update came out
- Not having updated since then
- Actually being willing to share a dump of the game
It's the third part that is the most difficult one, I guess. I mean, it is possible. I once activated a PS4 with a PSN account in order to activate Remote Play natively and held out on updating until the next exploit (after which other means of getting Remote Play to work on a hacked PS4 surfaced). Therefore it is not impossible, but I would not get my hopes up that someone did this accidentally and now realizes "Oh, I can dump Beat Saber. How convenient."
