Gamasutra has posted a interview they did with Dan Adelman, who is the man responsible at Nintendo for working with indie developers. Some of the highlights:
*Mentioning that Nintendo has dropped the requirement that developers have to have a office separate from their home
*Mentioned stuff like eShop developers getting to choose their price (citing the example of
Little Inferno starting at $14.99, the the developer put it on sale at $9.99 and deciding it was selling so well that they would keep it at that price) and that patching games are easy
*Nintendo has started providing Unity Pro 4 (which normally costs $1,500) free of cost to licensed developers, pointing out how this will make it easy for developers with Unity and a Wii U dev kit to port a game from Unity to Wii U and vice-versa. Also said that at GDC they will unveil new tools for developers to use HTML5 and JavaScript to make games
*Mentioned that Nintendo has dropped the requirement for digital games after WiiWare to sell a minimum number of copies before developers get revenue. This means that for DSiWare, 3DS eShop, and Wii U eShop, developers get revenue the moment they sell any copies.
*They worked and continue to work with developers on feedback for stuff like what functionality they want in the eShop, how they can make developer tools better, etc. They also try to make it easier to interact with, making sure to answer any question or at least reply within 24 hours.
