Apple just sent invites for a September 9 announcement - just under two weeks away. The announcement is expected to center around a new iPhone, likely called the iPhone 6s (and iPhone 6s Plus). Rumors are also circulating around a new Apple TV that would finally have an App Store. I'm crossing my fingers for that one.
The tagline on the invitation for this event is "Hey Siri, give us a Hint." so I decided to ask Siri for a hint.
