So, when's the next OS update?

Seeing as nothing was released at I/O, when do you think the next OS update will come?

The next Nexii are still a very long way away and I heard a rumour about the 10th, but it was one small site (which I can't even remember) and was fairly vague.

Or, for those who are subscribed, did MKBHD hit the nail on the head? Does the movement of so many system apps to the Play Store show Google taking control via app update, meaning less and less frequent system updates?
