Analysts have begun making their predictions about the iPhone 5’s odds of success for launch weekend sales, and in fact there’s quite a range when it comes to how the experts see things shaking out. After Apple unveiled iPhone 5 pre-order totals of 2 million over 24 hours, double the 1 million the iPhone 4S managed, it would seem like multiplying out the 4S launch weekend total of 4 million total sales is a safe bet. But that’s not necessarily the tack all industry analysts are taking.
