Ubisoft has made clear that neither the Nintendo Wii U or the Nintendo 3DS will be part of their presentation this year at E3. Responding to a question on which platforms will be showing up, a Ubisoft representative let it be known that they will not be showing off any games on any Nintendo platform.
That’s not to say that Ubisoft has given up on Nintendo hardware. Ubisoft continues to develop AAA games for multiple platforms - Watch Dogs will be delivered to Wii U as well as Xbox One, Xbox 360, PlayStation 4, PlayStation 3, and the PC.
*Watch Dogs is, on the other hand, delayed several months after the May 27th release of the title for all other platforms.

Back near the end of 2013, Ubisoft made clear that they’d be reevaluating their commitment to Nintendo hardware as they’d seen less-than-ideal sales on games in recent years. Ubisoft leaving Nintendo hardware entirely would strike a significant blow to Nintendo’s platforms if they ever did part ways - the fewer big-name developers stick with Nintendo, the smaller the chance is that they’ll stick around themselves.
