Zen Studios will have big Wii U news coming very soon. This is what the studio said after a fan shared some concerns about the lack of updates.
One of the administrators, named crackervizzo, had the following to say on the matter: ''Actually, we will have some very big Wii U news very soon. This is a difficult platform to support from a technology standpoint. Simple patches are not simple. New content additions are not easy due to the way the system is set up. We are committed to supporting Wii U. Again, please look for an announcement in the coming weeks. Thanks for supporting Zen Studios.''
Zen Studios has released various pinball games and Castlestorm on the Wii U with overwhelmingly positive feedback for most offerings. Their latest title, KickBeat, will be also coming to the Nintendo eShop at some point.
