EA made it clear that they don't consider the Wii U a hot product for the holidays; Peter Moore, in response to an analyst question, said "you're probably right that Wii U got a lackluster response" at E3. More to the point, EA hasn't announced any other titles than Mass Effect 3 for the Wii U. No other big spending on the Wii U or next-gen consoles was noted, nor is their forecasting specifically calling out the Wii U as a major positive coming up. Translation: EA doesn't expect great sales from the Wii U.
Still, EA will no doubt be "opportunistic" as interim CFO Ken Barker noted. That means if the Wii U takes off, EA will jump on it, even though it means getting to the party late. This is pretty much how EA (and other major publishers) approached the Wii last time; little support at launch, but once it proved a hit resources were shifted to take advantage of it. The minimum 1-year delay this causes will not help the Wii U in its quest to get established. The other implication of this is that EA will not be putting great effort into specific Wii U development; any titles that are started are likely to be ports, without much resource spent on adapting to the gamepad controller.
