Next month's Jump Festa in Japan will be celebrating the first appearance of the Pokémon franchise at the expo, and it looks as though fans might be in for a special treat. In the latest edition of Jump's official magazine, the company promised that Jump Festa would provide a "big surprise" at the Pokémon booth.

Naturally, you'd expect the event organiser to be doing what it can to generate anticipation, but it's been a particularly busy year for Pokémon announcements, so it would be unwise to rule anything out. Jump Festa starts on December 17th, so we've got a short while to wait yet. Speculation is already rife and varied as to what this revelation could be - what are you hoping for?
