If that is really making it into the next iPhone, TSMC is very well on track. Not so delayed as everyone was claiming here.
I wonder if Apple really is going quad core. It wouldn't quite fit my theory that Apple is smarter than the others, knowing that more than two cores are a waste in mobile applications. I really hope Apple is not going after this bigger, faster and more bullshit like Samsung.
The sapphire screen may already be more expensive than that (don't want to know how much energy the production cost - sapphire is almost as hard as diamond). Apple should concentrate on things like software, ecosystem and device quality - that's where Android devices suck. They don't have the margins to improve much (see the plastic S5 - Samsung will soon lack money for those expensive fabs ;-) ).
