Well if this is true that means no upfront cost for indie developers, and currently the eShop is probably the most friendly of the console online services right now. (Since I don't know what Sony has planned for the PS4, which is a long way from GDC 2006 where they proclaimed that there is no way they would need indie developers to help the PS3. And Microsoft currently has a system that punishes the developer if they need to fix an error.
The only "problem" is the approval process, which I don't think is that much of a problem, making sure the games that potentially are going to get published are not violating any IP, and are playable is a lot better then Apple and Google's Laissez-faire, which allows good games to buried by horrible free games (I'm not saying all free games are horrible) and only takes action on IP infringment if there is a possiblity of lawyers knocking on the door isn't that great of the plan. And is simular to how Atari ran things before they ran the market into the ground.
And according to indie's that do develop for both mobile and for the eShop there is a better chance for a profit on the eShop since it is self contained and regulated. The orginal comment was about Wii's Wiiware service, I expect eShop will be better since NIntendo got rid of the minimum sold requirement and is lowering the publishers, Nintendo's cut, and some other requirments such as having a dedicated office address.
