What I think they should do is release a portable only version or a smaller version that's cheeper. However I think this new version will just come with a better kickstand and better battery life.
Wall Street Journal wrote:TOKYO— Nintendo Co. NTDOY 2.16% plans to release a new version of its Switch videogame console next year to maintain the sales momentum of the device, according to suppliers and others with direct knowledge of the plan. Nintendo is still debating what new hardware and software features to include in the upgrade and weighing the cost of the features, people with knowledge of the discussions said. One option is improving the display, they said. The current Switch uses a lower-end liquid-crystal display without some technologies that are standard in more recent smartphone LCDs.Updating the display with these technologies would make it brighter, thinner and more energy-efficient. The updated Switch isn’t expected to adopt the organic light-emitting diode or OLED panels used in Apple Inc.’s AAPL -1.62% iPhone X series. Nintendo is looking to release the new Switch in the latter half of 2019, perhaps as soon as summer, the people said.
