Nintendo has registered a bunch of new trademarks, 12 of which could be future Pokemon titles. Some of these include Pokemon Red, Green, Blue and Yellow, familiar? Some stranger ones you won't recognise are Black, Brown, White, Gray, Scarlet, Purple and Crimson. While these don't always mean new games, it would have been nice to see Gold and Silver somewhere in there. Yes we want a remake..
