Sorry guys, having a boosted (clock-wise) CPU and GPU is not enough to warrant calling the thing a "separate platform to develop for." All of the architectural quirks remain the same. I could see the added cost and effort being an order of magnitude less than a PC port as you are only adding one SKU with very, very similar hardware, rather than thousands of possible combinations with quite different hardware.
This to me seems more like an Iphone 6/6s situation. There really isn't that much inhibiting vertical integration here like with multiplats.
This is also different from the 3DS in that the games are console games with console level budgets (and the costs of developing for different hardware don't scale proportionally with budget) and the 3DS games were majorly single-platform exclusives.
