The number of mega pickles didn't influence me much either, I am quite happy with 20x30 prints from 10MP and any of the numerous AP members that have seen said prints will probably agree. Time moves on and if they can deliver results at 36mp then bring it on.
They already surpassed their competitors( at a price premium ) with the D3x and 24 mp so if the extra resolution is as good as expected then they have nothing to worry about. They are after all a company that is required to earn money ( profit ) and not a benevolent institution for photographers but if history is correct they have a habit of being a little late to the game but at least when they get there the product is polished.
