Chris Morris, in a post at GamesIndustry International:
Yves Guillemot, Chairman and CEO of Ubisoft, is typically one of the biggest proponents of new systems, but betting big on the Wii U didn't work out well for the company. ZombiU, one of the most popular launch titles for the system with players, was not profitable, he says. Not even close. As such, he says, there are no plans (or even desire) for a sequel.
As I've written about previously, the Nintendo WiiU isn't selling particularly well. It seems as though the poor console sales numbers have translated into poor sales numbers for games. In the article, Morris notes that EA does not currently have any games in development for the WiiU. When one of the largest videogame dev shops in the world doesn't have games in development for your platform, you're in a tough spot.
Folks, everyone is going to want to play Nintendo's first party software (e.g. Mario, Zelda, Metroid). That's a virtual certainty. Unfortunately, it's unclear if gamers and third party developers will stick around for the long haul.
