Gamertell via Brawl Central reports that Kiosks in Japan are having demos of the title set up this weekend. There have also been recent rumors floating around the internet that US gamers will soon be sampling the game as well.
Brawl Central reported that GameStop stores will be receiving demos of Super Smash Brothers Brawl very soon. A source confided to the site's writer that the game demos may be at GameStop Wii kiosks by next week. The author of the article then called local GameStop, which confirmed that the demos could be available by then. I guess this means its time to start stalking GameStop stores.
Below is a video, taken by a Japanese fan from one of the demo kiosks.
