Now here's a bit of speculation to chew on. There have been no official announcements, but Go Nintendo has put up an image of a flyer which states that High Voltage's highly-anticipated Wii FPS The Conduit will be at this year's Penny Arcade Expo... as part of the Nintendo booth. That is, it will be displayed at PAX alongside Nintendo's own first-party games.
At E3, High Voltage had to make off-site appointments to show off the game because they didn't have a publisher, and so didn't have a booth. Why is Nintendo suddenly playing host to them at PAX? Did High Voltage cut some kind of deal with Nintendo to get floor space? Possible, but... does Nintendo intend to publish the Conduit themselves?
