For what it's worth, it seems like in recent times every 3rd release goes out broadly. I would be absolutely shocked if this didn't, at the minimum, go out to the majority of the existing FSD fleet. Not that Tesla seems to care but with every limited release the outrage seems to increase exponentially.
Call it blind hope but I wouldn't be surprised if this also goes out to new testers. The fact that Elon said it was going to new people and now we have an "insider" claiming the same thing for this build is a good sign. Today internal, Monday insiders, Tuesday pause (scary), Wednesday wider release, and by the weekend new people.
It's also a week sooner than we would normally expect, which hints at pressure inside the FSD dept. to meet the promises of new people.
As always I'll remain hopefully skeptical.
