If a majority of EA's upcoming games use DICE's Frostbite Engine 3 and the Frostbite Engine 3 doesn't support the Wii U then it doesn't take a genius to come to the conclusion that a whole lot of upcoming EA games will not be coming to the Wii U.
This story begins with a recent tweet from DICE technical director Johan Anderson, who responds to a question about the company's Frostbite 3 engine running on the Wii U.
He claims that some initial test on the Wii U using Frostbite Engine 2 delivered some less than stellar performance results on the platform. This led to a decision not to support Frostbite Engine 3 on the platform.
@mutedpenguin 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— Johan Andersson (@repi) May 6, 2013
So it stands to reason that if a game is being developed using the new engine it will not be coming to the Wii U. According to this NeoGAF forum thread there are at least 15 games being developed right now that use DICE's new engine including Battlefield 4, Mass Effect 4, Dragon Age 3, Army of Two: The Devil's Cartel, Need For Speed 2013 and several unannounced Star Wars titles from Visceral and DICE. After E3 next month you can probably expect to see that list grow even more...
