One problem with the Nintendo Network ID system is that you cannot currently transfer them between consoles. This of course means you can't nip over to your friend's house and sign in to your own NNID, and more crucially should anything happen to your Wii U you'll be reliant on Nintendo customer services to retrieve the purchases you made with it.
This is one reason some may be wary of purchasing games from the Wii U eShop - nobody wants to buy a game only to lose it because something happens to their console. With this in mind someone asked Trine 2: Director's Cut developer Frozenbyte on YouTube whether or not a physical version of the game would ever be released. Frozenbyte replied:
It's a possibility... we'd need a partner for it though, so even if we decide to go for it, it will in any case take a lot of time to arrange, so it's hard to say when it could happen... we'll see!
It seems the developer is open to the idea but the likelihood is still fairly low, considering it would need to find a partner and sales would be a little unpredictable due to many already downloading it from the Wii U eShop. A retail release would also most likely be more expensive than the download version, which may put many people off. Nintendo has said that in the future people will be able to transfer their NNIDs between Nintendo consoles and PCs so hopefully this ongoing problem will be rectified soon.
