Going to 1080p is not going to massively alter the development cost.
It's not like PC games cost way more because they support 5-6 different resolutions.
My guess is if you're using the TV screen + the Wii U display (which requires a second frame buffer), 720p is about the max you can get from the machine unless you are displaying very basic graphics.
