"Sources say consumers should expect a range of prices for different models including lower-priced versions."
That's just standard "we don't actually know what the hell we're talking about so we'll hedge in every direction so we can try to claim we were correct after the fact" Apple rumor talk. Their sources could well be their own posteriors and a drunk at the bar who's vague hand gestures seem to indicate a broad range of prices and features.
