Yes, I saw that. But I didn't invest in it too heavily, as it was a preview, and I thought some things might be added/dropped/changed.

I hope he follows up with the final exposition (in case anything changed), or makes this one official. I find this a bit easier to understand than the official perldelta, though that is the reference in case of debates.

The way my mind works, if I see some factoid that turns out not to be true, it's very hard to correct it. So I'm not terribly interested in a list of "these might happen", except as a discussion on some particular feature.
