According to a tweet from DICE's technical director Joham Andersson, DICE never bothered to test the Frostbite3 engine on Nintendo's Wii U, based on unsatisfactory results stemming from testing Frostbite 2.
Andersson's tweet came as a response to a fan who claimed that the engine was once running fine on the platform, but then bizarrely halted. He set the record straight saying, "FB3 has never been running on WiiU. We did some tests with not too promising results with FB2 & chose not to go down that path."
With an earlier tweet that all future Star Wars games would be made on that engine, as is the new Battlefield, it's not a far leap to say that unless DICE pulls off some serious technical magic soon, these games and plenty others won't be seeing the light of day on Nintendo's latest console.
Couple this with earlier statements from DICE exec Patrick Bach, who trumpeted that the Battlefield 4 wouldn't feature motion controls, something of a draw for Nintendo's Wii U, and the writing is on the wall.
Similarly, there was nary a mention of the Wii U in EA's investor call earlier today.
However, all hope may not be lost for Star Wars. When it was revealed that the future of the galaxy "far, far away" was in EA's hand, labels president Frank Gibeau had cited two other studios would be developing Star Wars titles besides DICE. Namely, Visceral and BioWare.
However, Gibeau did say that Frostbite would be the primary engine for the Star Wars games, which does kind of limit options for Nintendo after all. But EA has gone back on their word before. The studio is planning "a full reveal at E3 including more next generation titles in development," as well as a better look at Frostbite3.
