The official Pokemon website has recently announced that big news is coming on January 8th. This comes just an hour or two after the official Japanese Pokemon website posted an update about it. What does this mean? We'll find out for sure on January 8th (possibly midday January 7th, due to the time difference in Japan), but whatever it is, it is likely to be a major announcement.
The announcements of Pokemon Black 2 and Pokemon White 2 were held in a similar manner, with both the international and Japanese sites making a simultaneous announcement about the new games.
There are a few possibilities of what they're planning on announcing. I'm going to give my opinion on three different possibilities I've been hearing a lot about regarding what these games could be.
