Playstation 3 festival coming late October?

According to the-magicbox, Sony is going to be holding an entertainment festival dubbed Akihabara Enta Matsuri in Tokyo starting on October 22 and ending on the 30. They don't detail whether or not any games are to be playable or what they're going to be doing at this festival that will keep people entertained for 8 days but I guess we'll see.
