According to a preview to the Japanese show, Pokemon Smash, Junichi Masuda (GameFreak) will be in person on next week's episode to showcase a new Pokemon. Following the preview, the Pokemon Facebook updated its status telling fans to, "wait until next Saturday for Pokemon X/Y news". The "reveal" will be posted world-wide all at the same time, as Nintendo deems this as something SUPER important. So, put your hype hats on and board the S.S. Hype, folks, here we go.
