Just one hour ago the official Pokemon Twitter account tweeted:
https://twitter.com/Pokemon/status/378911540792942592Heads up, Trainers! We've got a surprise for you! Tune in Monday at 8 a.m. PDT for a special announcement!
What could this surprise be? Will it be worthwhile? It doesn't say outright that it's related to Pokemon X&Y, so it could be anything. Perhaps a formal reveal of the website that was leaked a few days ago, GottaCatchEmAll.com? Any thoughts?
