Martin Pichlmair, developer for the eshop game Chasing Aurora told the Official Nintendo Magazine something similar.
I can not talk about the new eShop in detail. What I do know is that Nintendo is doing everything to make this console much more open, social and indie-friendly than the Wii ever was.
He further added that the new console lets developers do a lot of experimenting; resulting in births of great ideas.
There are people at Nintendo who know where innovative games come from. And if you look at the launch lineup you can clearly see that those people have had a say in it. At the same time, the Wii U with its various controller configurations calls for experimental games of all kinds and Nintendo is always eager to have games make good use of its console’s innovations.
Nintendo has enforced a lot of licensing and quality control barriers on the Wii Shop, making the lives of developers a tad hard. However, the Wii U looks to support developers more and also grant them more freedom.
