Other changes undiscovered
Apple has issued a minor firmware update for the Apple TV, v6.0.1. The main addition appears to be an iMovie Theater channel, used to view videos uploaded through iMovie on other devices. Any other changes have yet to be uncovered, since Apple typically doesn't provide release notes alongside Apple TV updates.
A rumored Apple TV hardware refresh was absent during this Tuesday's iPad event. A day before, though, it was indicated that the product had been delayed. Apple is believed to be working on a new TV control scheme, which could appear in a new set-top, but might also come to a full-scale HDTV.
