In an interview with an internet radio station, Nintendo of Canada’s Director of Marketing, Pierre-Paul Trepanier, confirmed that the Revmote will feature force feedback and that “[Nintendo] will show more at E3”. The interview was conducted in French, so whether or not he was referring only to a rumble feature or something more complex is up to interpretation. I would imagine he was referring only to the standard rumble feature. Of course, Nintendo has yet to reveal the other “big secret” about the Revolution, so who knows?
