Pokemon Ruby and Sapphire Remakes hinted ?

A new BW2 commercial has appeared on Japanese television today (yes, they're still advertising the games), and at the end of it, there is a title card announcement which states "We at Pokemon want to share the latest news with you. Scheduled announcement: January 8th." Obviously Pokemon plans to make a big announcement.
Gamefreak director Junichi Masuda revealed on his Twitter in December that he had just filmed an episode of Pokemon Smash, and since the episodes are recorded a month or so in advance, it's likely the episode he taped will air in January. Masuda usually appears on Pokemon Smash to make game announcements.
