Konami will be holding a Metal Gear Solid Peace Walker completion ceremony on Wednesday. Even if you think you know all there is to know about Peace Walker, you may want to tune in.

Tweeted Hideo Kojima earlier today: "On Wednesday, there will be a big Peace Walker announcement. I don't think you can understand the enjoyment of Peace Walker until you've played it, but I believe you'll feel a hint of sorts about 'where is it a new Metal?'."

It's difficult to tell if Kojima is referring to a single big announcement or just a bunch of announcements that are big when taken together. We'll have to wait until Wednesday to find out.

You may want to turn to Kojima's Twitter for hints. He's been posting images from the event's rehearsal throughout the day.

First came a look at a lunch meeting with the event's MCs.

He did not say who the MCs are, unfortunately. He did provide a look at what he ate: a meat dish of some form and a banana tart.

Later, Kojima provided a look inside the event space, complete with pics of the giant nine meter screen that will run Peace Walker footage:

The text in the pics say "Opening Video" and "Metal Gear Solid Peace Walker Completion Ceremony."

Be sure and check back on Wednesday at 13:00 for some possible Peace Walker surprises. As detailed last week, Konami will be allowing a few members of the general public in to provide live updates via Twitter.
