It's good to be skeptical about such things. Normally I would be in the same boat. However, the logos, along with the website url that just links back to Pokemon.com right now have me pretty convinced. Pokemon Gray and Delta Emerald may have been trademarked, but they didn't come with high quality logos the day before a major Pokemon announcement. Also, Gray and Delta Emerald were obviously linked to existing games in some way, as it was Game Freak insuring they had room to work. Sun and Moon are oddly random and specific. So unless Game Freak is trying to trick us on purpose, I think it's going to happen. I guess we'll know either way in seven and a half hours.
