Jim Dalrymple from the Loop Who is considered to be an authoritative source of info on Apple news and is used by Apple to release information to the public. Jim now hints that Apple will hold separate iPhone 5 and iPad mini.
Jim quotes John Gruber
I’m thinking it makes more sense for Apple to hold two events. First, an iPhone event, focused solely on the new iPhone and iOS 6. Then, the iPhone ships nine days later, and there’s another wave of iPhone-focused attention as the reviews come out. Then, in the first or second week of October, Apple holds its traditional “music event”, exactly along the lines of the events at which they’ve been debuting new iPods for the last decade.
Oh that Gruber is a smart fellow.
