Per the official site, EA is working on a mobile version of its in-house graphics engine called Frostbite Go.
One of our most exciting current projects is called Frostbite Go, a mobile division empowering EA game developers with Frostbite’s proven excellent workflows and features to bring true Frostbite experiences to all major mobile platforms.
Despite the engine being devoloped to scale down to the mobile platforms, it appears the Wii U is still out of luck. The site notes elsewhere that “diverse targets from XBOX360 and PlayStation 4 to iOS and Android” are supported. EA and DICE have said that the absence of upcoming Wii U versions of Frostbite games was due to technical difficulties in porting the games over to the less robust hardware. As late as last week, DICE technical director Johan Andersson tweeted that they were not able to get the Frostbite engine running on Nintendo’s Wii U hardware which was the reason why they abandoned that effort.
With at least 15 games on EA’s schedule slated to use Frostbite, the Wii U could be left out of many EA games.
