I'm not expecting Gen 7, but I'm not expecting XY2 either. Something in between is much more likely, a companion game to XY, with more Pokemon and an expanded Kalos region to explore.
Girls, I'm not trying to get excited, but February 27th is going to be "Pokemon Day," and the officials Pokemon Twitch is going to stream gameplay/interviews/and episodes of the anime for over 24 hours. They have to announce somethings decent in the direct since it's a day before, right?
