Microsoft used last year's keynote to announce a flood of Japanese Xbox 360 support.

CESA has announced the keynote speakers for this year's Tokyo Game Show. The annual event will be held this year from September 15 through 18 at the Makuhari Messe in Chiba.

The keynote, held on the 15th, will be split into three parts this year. Speaking first from 10:30 to 11:00 will be CESA chairman and Square Enix CEO Yoichi Wada. His speech is titled (roughly translated from Japanese) "The Essence of Game Industry Revolution."

Following Wada, Sony Computer Entertainment Worldwide Studio President Shuhei Yoshida and Senior Vice President Yoshio Matsumoto will take the stage from 11:10 to 12:00 for a speech tentatively titled "All About PlayStation Vita" (again, this is an unofficial translation of the speech name). The speech promises detailed specs and the latest information about the Vita's software lineup.

The third speaker will be Yoshikazu Tanaka, CEO of social gaming giant GREE. He will speak from 12:10 to 13:00 about the social games market.
