Reason being?

As I think I’ve laid out in this thread 3x now: we’ve frequently seen 6 betas for a point release. We are on number 5 and number 6 would drop early next week (5/13 or 14). In all likelihood, that will also be the release candidate build. If that pans out, that same build will be released to the public on or about 5/20.

5/27 is Memorial Day and begins the short week prior to WWDC. It stands to reason that Apple will not release a major feature update in a short week during which its engineers are gearing up to the most significant software event of the Apple year. They are pushing the envelope a bit, as it is, given the importance of the TV updates coming with 12.3.

Dark horse candidates for release dates:

-next week (5/13): certainly possible, which would make beta 5 the release candidate build. I don’t recall Apple stopping at 5 betas before, but where we find ourselves on the overall version release calendar might make that a bit more realistic than normal.

-With iOS 13 beta 1 at WWDC on 6/3 or 6/4: No reason it couldn’t since most users will not be on the betas. Seems unlikely, though, in that a major functionality update would be overshadowed by iOS 13

So, there you have my own speculation, which is nothing more than that.
 
Queue the 15000 posts saying ‘it’s not here’, ‘it’s here’, ‘I’m downloading now’, ‘when’s the public release’!
 
Can’t be final as not a full delta update still a beta one so if it’s gonna release on Monday they would just of waited I think this is final with beta extras and 2 weeks full release
