While the Vita launched with full retail games available via both the PSN and retail shops everywhere, the 3DS has been kicking the idea around for some time. At a financial results meeting in Japan, Nintendo has revealed that the first full game available via the eShop and retail will be New Super Mario Bros 2.
The company detailed that consumers will be able to purchase the software at retail either as a boxed cartridge or as a download code for the 3DS eShop. Nintendo has also stated that digital downloads of full retail games will be available at launch for the Wii U.
We'll have more information on New Super Mario Bros 2 at E3 and beyond.
