Sources close to the Wall Street Journal have been told that Nintendo is currently distributing software kits for their upcoming NX platform. This suggests that it’s likely that the product will be introduced next year. Nintendo has previously said that they won’t be publicly talking about the Nintendo NX until 2016.

Nintendo Co. has begun distributing a software development kit for its new NX videogame platform, people familiar with the matter said, suggesting the company is on track to introduce the product as early as next year.

The exact shape of the NX hardware isn’t yet clear. People familiar with the development plans said Nintendo would likely include both a console and at least one mobile unit that could either be used in conjunction with the console or taken on the road for separate use. They also said Nintendo would aim to put industry-leading chips in the NX devices, after criticism that the Wii U’s capabilities didn’t match those of competitors.
