If you believe the latest rumors, it appears as if you'll be seeing a cheaper and smaller edition of the Nintendo Switch sometime in the Fall of 2019. The report is coming from Nikkei, who claim that there are two different versions of the Switch currently in production and testing phases as you'll be seeing a more enhanced and robust version that has no timeframe attached, but that a smaller one that will still connect to your TV but be easier to take with you and play as a handheld console will be revealed sometime this summer and make its way into the marker a few months later.
It sounds like a good idea on paper, but if it is real, that begs the question of how big the smaller version will be and how much memory it will contain. The regular version already only comes with 32GB without any microSD improvements. If the report is right, the best place to show it off would be E3 2019, provided the company doesn't just have a Nintendo Direct before the event like they did last year. Only time will tell if this is true or not as we approach June.
