You mean Tweets like this one saying that, despite being sad, he’s still working on the update?

No, being sad on Twitter is not solid evidence of delay before the delay happens. None of us knew how much longer he needed to work on it, and we had no reason to assume his personal issues would prevent him from meeting a deadline that he himself had set. We only found out about the delay after it happened, and what you may have found on Twitter is being used to rationalize it post-hoc.
And while I empathize with him, those personal issues are also not a valid reason why he couldn’t spend the 15 minutes required to send out a Tweet and take down that incorrect release date from the main page.
