So I was thinking about it... Last time around, the 4 was $200 / $300 for 16GB and 32GB respectively. Now it's $200 / $300 / $400 for 16, 32, 64. I would bet that in the next phone or two, the 16GB will be dropped and the top end might end up with a 128GB version at $500 (with the other pricing staying the same). Apple is slowing turning up the heat on the price, and we're not jumping out of the water. Pretty good tactic to raise the cost without people realizing it.
