Nintendo NX is a Handheld/Console Hybrid With Detachable Controllers
The most detailed and likely to be true rumors about Nintendo's upcoming NX have made their way to Eurogamer.
According to sources, the NX will be a powerful handheld device that houses two detachable controllers on either side of the portable. This way, players can take their console experience on-the-go with them and even have local multiplayer experiences with their friends. The NX will also feature a TV dock, which will allow players to take their NX gaming experiences to the big screen.
In a second article, Eurogamer's Digital Foundry reported that the NX will likely be powered by the Nvidia Tegra X1 mobile processor. This is the same processor that has been used in recent Android powered tablets, such as the Nvidia Shield, and the Google Pixel C. If Nintendo uses their own OS for the system, they could potentially get more power out of it than the Android tablets do. Still, this would be a significantly less powerful piece of hardware when compared to the PS4 or the Xbox One.
Again it seems like Nintendo is sticking to their notion of not competing with Sony or Microsoft. Interestingly though, a third source suggests that Nintendo could be using the Nvidia Tegra X2, rather than the X1. Little is known about the X2 at this time, but one thing is for certain, it would give the NX the power it needs to complete with the PS4 and Xbox One. This would be a smarter choice, seeing as the NX may look extremely weak by the time the Neo and Project Scorpion hit the market.
It looks like the rumors about the cartridges may be accurate after all. According to reliable sources, the NX will use cartridges in favor of discs. Nintendo is even recommending 32GB cartridges to developers, which is notably smaller in size compared to Blu-Ray discs. For example, last year's Halo 5: Guardians took up a whopping 60GB to install on Xbox One. That is a huge gap in file sizes for Nintendo's new device. Of course you can also download games digitally, if you do not want the physical media.
An additional, and rather disappointing rumor, includes that the console will most likely not be backwards compatible with Wii U games, a first for a Nintendo console. With the drastic change in processor type, and the unique nature of the device, emulating Wii U software would be difficult. Perhaps this is why sources say Nintendo plans to create NX ports of popular Wii U games such as Super Smash Bros. and Splatoon.
One final rumor is that the console is set to be announced sometime in September (perhaps during the Tokyo Game Show). The NX is still slated for a March 2017 release.
