It released a Classic Mini SNES. You can see the patent below, via a Japanese trademark Twitter bot.
The SNES Classic Mini is the 16-bit, retro version of the SNES, but it only comes with 21 games out of the box - we can assume that a lot of them involve moustached men in dungarees - and "Cluster" does not feel that this is enough.
Though Nintendo is now more into mobile games, the Game Boy holds a nostalgic value to the fans. Why file this trademark now if not to prepare for a new system? With the NES Classic re-release happening in Summer 2018 there is really no reason for Nintendo to add another retro system into the mix next year.
A trademark citing does not always mean a real product, but a fact that can't be denied is Nintendo's Classic Edition brand has enjoyed a massive success. There were 1,049 games released for the handheld, so Nintendo shouldn't have any trouble choosing a couple of dozen. In five months before going out of stock due to heavy demand, the NES Classic sold 2.3 million units, notes Fortune. In July, the company filed a similar trademark application that included an image of the Nintendo 64 controller. That move seems even more likely as the 30th anniversary of the first Game Boy will happen in 2019.
You do have to do a little reading to learn how to make use of the tool and to accomplish the process which might not be for everyone, but the option is now there and all you have to do is find the games (which of course we recommend to dump your own cartridges as downloading the would not be lawful).
