A Linkedin profile for WayForward engineer Brian Valdillez revealed that the studio was working on a now cancelled Wii U project in 2012.
In Valdillez's projects is a listing for "Pictionary Universe", planned for release in 2012, with "recording and replay capabilities designed for uploading to Miiverse", according to the listing. The game, now cancelled, didn't come to fruition publicly so is likely to have been a proof of concept that perhaps didn't go according to plan.
Publisher THQ did dabble in Pictionary before, however, having released a version for Nintendo Wii in 2010.
Would you have wanted a version Pictionary for Wii U?
