Brian Davis, Gameplay Programmer at Next Level Games, updated his Twitter status this evening with some interesting news from Pax 2013:

Nintendo promoted the Sentai inspired title at PAX this year, and those in attendance got the chance to actually purchase a copy early. After hearing about the poor sales of The Wonderful 101 in Japan, this is really promising news, and might even be a predictor of North American sales when the game debuts on September 15th for Wii U. I guess we'll see what happens in the next couple of weeks.
