There will be NO LQMT in ANY Apple product in 2013. There could (and should) be LQMT in what they're banking on as the next game changer in mid to late 2014 - the watch.
I see no reason for LQMT in the iphone or ipad. What's the point? The fit and finish of the hardware is already top-notch. No one's complaining too much about durability. If they're going to this much effort to introduce LQMT into a product line, you can bet it's going to be something iconic.
