Earlier this week, Daring Fireball's John Gruber floated Tuesday, October 13 as a potential date for Apple to hand out iPhone Duo review units to selected reviewers in person, and it appears that he might have been on to something. Bloomberg's Mark Gurman today reported that Apple plans to unveil its all-new smart home hub, a second-generation HomePod mini, and a new Apple TV 4K model on October 13, the same date that Gruber mentioned in his speculative piece a few days ago.
