The statement also describes the retail availability of codes for these digital games, which are described as "16-digit codes" for the "Nintendo eShop." So the Wii U's store is going to be called the eShop, just like the 3DS's, and use the same kind of codes. Between a unified store branding, availability of redeemable codes, and digital sales of full games, it looks like Nintendo is finally moving in the right direction in terms of the internet.
Now if it would only let you redeem those games to an account instead of a single 3DS. During last night's presentation, Satoru Iwata said that the new downloadable 3DS retail games "will be stored in the consumer's SD memory card and be playable only with the hardware to which it was downloaded so that, unlike how you can share the packaged software which are stored in game card format, the consumer cannot share the software with other Nintendo 3DS systems owned by other members of the family or friends." In other words, they'll operate just like eShop games operate now.
