It appears as if we won't see any new Ubisoft titles on Nintendo 3DS and Wii U at E3 next month. A representative for Ubisoft told Nintendo World Report that there won't be any new titles shown.
"We won't be showing off any Nintendo games at E3 this year."
The report is likely the result of Nintendo World Report trying to book an E3 appointment with Ubisoft and getting this reply. We would, however, be very surprised if Ubisoft didn't have a new Just Dance title lined up for Wii U this holiday season. Ubisoft have been one of Wii U's top supporter ever since launch, but support certainly doesn't appear as strong as it once were.
