What could it be?

At the start of this week you may have seen the news that Pokémon Director Junichi Masuda teased something for Sunday, saying that all would be revealed on Japanese TV show Pokémon Smash. Speculation naturally followed, and Masuda has decided to up the ante with a post on his English-translated Game Freak blog page. His post is below, and this is the official translation.

IMPORTANT NEWS!!

On this coming Sunday, Februrary 26, 2012, from 7:30 A.M,
I, Masuda, will be appearing on TV TOKYO’s Show, “Pokémon Smash!”

Not only that.
And there…

I will be making a VERY important announcement,
so be sure not to miss it!!

Watch it live on TV!

And, for those of you who can’t watch television on live,
I will announce the same information right after the show via twitter!!

Everyone, I hope you all enjoy the show!!

Once again no details are given, and before you all get too excited bear in mind this could just be a new monster, distribution event or something specific to Japan. It's unclear, but judging from the generous usage of exclamation marks Junichi Masuda is excited; we'll see what happens on Sunday.
