i don't think EA wanted to support handheld especially during the DS/PSP era due to piracy. EA really concentrate more on home consoles and PC as their main targeted owners.
Ubisoft supported Nintendo on certain IPs, not sure if it started only on AC V: Unity or even Rogue on why they didn't want Wii U to have any of those titles. Agree above on Square Enix, Konami, Take 2 that don't have games for the Wii U. Capcom has for the 3Ds SFIV 3D. maybe Tatsunoku v Capcom game for the Wii? so it is not 10 years back they didn't support Nintendo. They aren't just relative enough to push games.
But capcom should release a SF V to the Wii U i hope maybe after the PS exclusivity. Konami should try the PES on Wii U especially Japan gamers that bought the Wii U i assume would love football (soccer) and can have good sales. especially EA doesn't have their Fifa franchise on the Wii U besides the legacy edition of Fifa which we all know isn't great.
