Nintendo has put out a press release that once again details how you can expect Nintendo's software to be downloaded. This pertains to the eShop for now, but will work with both 3DS and Wii U. Your three digital options are...

1. Download Cards
2. Download Codes
3. Directly through eShop

Each one has its benefits, depending on what type of gamer you are. There are important options here for younger kids and parents that aren't too sure on how these setups work. Should pan out nicely for everyone.
