Given Apple's track record of introducing something BIG every major revision of an iPhone, safe to say I'm believing all the hype about it. The biggest part about Assistant isn't just the integration into all the areas of iOS or with the Wolfram Alpha "decision engine", but the conversation workflow that it's rumored to have. Your IP5 will essentially continue asking you questions until it gets all the info it needs to execute a bunch of actions to execute the end result you want. That is Star Trek!
