Serebii.net has just updated with this:

CoroCoro is due any day now and will have new Pokémon X & Y details so keep checking back. We did have an image up briefly earlier, but quickly removed it due to our uncertainty about legitimacy. This may be amended throughout the day. If you have any ideas for the site, be sure to send them in
With the news of Pokémon X & Y, the Chatroom has been rife with discussion of the amazing showcase and speculation over contents while the WiFi Chatroom has been a place for people to hunt down the new Dream World Pokémon for trade and to battle other trainers so be sure to visit them. Our Forums have also had these discussion and are a bustling trade and competitive section for the games. Be sure to like our FaceBook Page.
