Developers are making games for a Nintendo 4K console that doesn't exist

Many people were surprised to learn that Nintendo Co.'s new video game console is missing a common feature of rival systems: support for high-fidelity, 4K graphics. Perhaps most perplexed were the numerous developers who were working on 4K games using a software toolkit provided by Nintendo. Employees at 11 game companies said their teams were in possession of Nintendo's 4K development kit for the Switch. The companies span the globe, ranging from large publishers to small studios and include at least one that has never made a console game before, Zynga Inc., according to the employees, who asked not to be identified because they weren't authorized to discuss their projects publicly. The latest model of the best-selling Nintendo Switch is set to go on sale Oct. 8.
