Or will it? As Hickey notes, Nintendo already offers app repositories through the Wii Shop and DSi Shop. The difference with the Wii U is that it’ll offer a wider variety of apps, beyond games and basic utilities.
But breadth of apps is not the best metric for a real app store, unless your definition is simply “a place to buy apps.” The way I see it, a true app store goes further by opening its doors to any developer. Whether there’s an approval process (a la iOS) or not (a la Android) doesn’t matter. What’s important is that anyone who knows how to code can contribute, so that the app selection grows in unexpected ways. You won’t find any great app stores that don’t allow this kind of outside development.
From Hickey’s report, I can’t tell whether Nintendo will open its app store to all developers, and I have my doubts. Game consoles are notoriously closed off to all but a select group of publishers. Microsoft’s Xbox 360 is the only system that comes close to allowing outside development, through Xbox Live Indie Games, and even those apps are relegated to the darkest corners of the Xbox Marketplace.
So while I don’t doubt that the Wii U will have a wider selection of apps than Nintendo’s other systems–Hickey mentions MLB.TV and social networks as possibilities–I’m skeptical that Nintendo will let any developer run wild with the Wii U’s crazy multi-screen technology. But I hope to be proven wrong.
