iQue Ltd. is a 100%-owned Nintendo subsidiary in China that was originally put together to sell versions of Nintendo products under a custom iQue-branded hardware. As Nintendo is now looking to make a bigger push into China with the Switch, the iQue brand/efforts aren't really needed anymore. What's the iQue gang going to do from here on out? It looks like they're shifting over to actual game development.
iQue is currently looking to hire both game programmers and testers to work on projects for Nintendo, although we don't have info on any specific games at this time. They'll most likely work in assisting Nintendo's other teams on projects before they crank something out themselves. We'll have to keep tabs on Nintendo's future releases to see if the iQue name pops up in the credits!
