According to NintendoWorldReport, Ubisoft will not have any Nintendo-based titles to show off at E3 2014. Ubisoft confirmed the sad news to the site earlier today.
"We won't be showing off any Nintendo games at E3 this year," a Ubisoft representative said.

At present, the only known Wii U title in development from Ubisoft is Watch Dogs. However, that version of the game has been delayed until at least Fall of 2014, if not later.
